Hi all, I've deleted a series of tweets today because I worry about their impact. I will restate the thread with zero snark or attempts at wryness, and without anything OTHER than the point I want to get across.

/1
Why did I delete it?

I worried most about it being misused by those who **distrust the science of covid**.

Why did I tweet it?

Because I care about the science of this pandemic very much, & about the scientific process that has led us to amazing vaccines & approaches.

/2
What did I regret about the tweet?

I wrote it angrily, because media has picked up on an *unequivocal statement* abt school closures effects on mental health when there is a lot of nuance on the data, & the source was a *favourite source* of mine, the Ontario Science table.

/3
The anger came from the frustration that a group that people turn to for science and trust it, would put out information in such a lopsided away, clearing any nuance as if it didn't exist.

/4
So what did I mean to say?

The Ontario Science Table, a generally excellent source of COVID information, did such a poor slide on the current science on the mental health and the pandemic that it has misled the media and parents and teachers about the state of the science.

/5
Not only was a peer reviewed report released the very same day that included data that would have certainly been important for such a slide (bad timing, zero fault), but similar data has been available since November in another peer reviewed journal.

/6
The science they did cite on MH impacts of school closures was lopsidedly and unfairly cited, and ignores many aspects of the science. A member of the public, reading it, would conclude that they said it so strongly because the evidence was strong.

/7
There are many pieces of primary evidence and collated evidence (original articles and meta-analyses) that show a mixed bag of outcomes good, neutral, and bad, and **very few** that separate pandemic effects from school closure effects.

/8
The frustration is that there is a *systematic* way to collect and report evidence, and a *narrative* (want to tell a story) way to collect and report evidence. Their slide is the latter not the former. I can't conclude motive but I can certainly identify the result.

/9
I do *not* mean to cause disrespect to the Table, but perhaps they don't or didn't understand the gravity of the misstep they made. It's huge. It's not a small mistake or an oops mistake, it's a massive mistake.

/10
Why does it matter?

Because this might not even be our last wave of the pandemic let alone the last pandemic. If the narrative of the science stands uncorrected & wrongly+ loudly proclaim school closures only harm childrens mental health, we will see more death & illness.

/11
And that really matters. I strongly believe that other considerations like the spread of the virus, the impact of that, what happens when teachers and parents get sick or die, and what it's like to go to school during this pandemic period, that play in.

/12
I am so frustrated at seeing people publish scientific articles about mental health using the weakest of evidence and making the strongest of statements.

/13
I have rarely ever deleted tweets. I do so only when I'm wrong or worried about the impact of my tweet on wrong things.

I will not delete this tweet, and I have written it in a way such that I am exceedingly proud of it and what it says.

/14
In the spirit of what science stands for, which is a rigorous, edited, challenged, revised, & systematic pursuit of the truth of our world, I hope it also serves as an olive branch such that the Science Table reach out to other mental health experts to produce a better slide.
/15
Maybe because I have challenged them so publicly and loudly I would not be invited, but there is good science to be read and processed and reporting it accurately and fairly is crucial to maintaining public trust.

/16
Should they ever want their work on mental health and kids reviewed by a colleague and expert who will critically and seriously evaluate the scientific claims of their information, I remain forever at their service.

I am still digesting an interesting report, but it makes me wonder... this is beyond my expertise or region, but I found this graph shocking.

What if the narrative we are being told about the needs of in person schooling is being disproportionately told by one demographic?
/1
Note: I do not have the expertise or knowledge to vet this, and I do not understand all of the political and social contexts that the report discusses.

I believe ( and i could be wrong ) that this is produced by a teachers union and might have some biases in it. Though i do not understand the issue well at all.

Do we have a good summary of surveys of parents/family's preference broken down by race and income?

This is a meta-analysis of the longitudinal studies done during the first months of the pandemic. It is a *systematic* review in which they methodically went through ALL the research they could find.

/1
Here are the results they reported from their systematic review.

/2
My frustration is that this is how science is performed, yet major organizations that know better are simply selecting the points they want. I have no doubt that they would cite "evidence of an increase" but ignore the rest of this metaanalysis.

I am more than happy to have so many people resonate with my messages and follow me (and I am SO GRATEFUL for followers!!!), but I cannot screen the # of followers I've gained in the past few days (6000ish). So, I'm going to play a game:

"Please unfollow me if..."
(A THREAD)
Please unfollow me if you wish to argue against Black Lives Mattering (literally the phrase too) or how we as Canadians live on the stolen and unceded land of Indigenous people, or you wish to argue against the phrase: "Trans women are women and trans men are men."

/1
Please unfollow me if you believe that "wokeism" is ruining science or whatever field you care about, and not the generations of lopsided power that has created significant systemic discrimination.

/1 FWIW, "Deaths of despair" as used today is an awful, fake, heterogeneous category that stigmatizes and "others" death and ignores many other "deaths of despair"

seattletimes.com/seattle-news/d…
/2 "Deaths of Despair" is a term invented by Princeton economist Anne Case / Angus Deaton that lumps deaths due to overdose, suicide, and alcohol consequences. Despite having different etiologies, courses, and timing of mortality.

Note: I respect both greatly & read their book.
/3 I get why someone would lump those three together, but a) that's not how mortality codes work and b) that's not how despair works. Mental health and psychological expertise was sorely missing.

/1 THREAD: I knew this day would come.

While pediatric societies & "hospital organizations" did "science by press release," breathlessly discussing a correlation on a parent survey or releasing a statement about 1 month of admissions in May 2021, I knew we would get REAL DATA.
/2 This day has arrived. We have the incredible article by Ray et al, showing that during the first 15 months of the pandemic, youth ER presentations of self harm, overdose, and hospital admissions of both decreased by ~18% in Ontario.

1.6 MILLION YOUTH

/3 There is OTHER data out of Ontario showing that acute mental health ER and admission levels DID NOT INCREASE during the first 12 months of the pandemic. (broken down by age group)

THEY DECREASED.

My anger is so high. all I wanted when @CHEO and @SickKidsNews announced these breathless claims about skyrocketing admissions and self harm was DATA RELEASES.

Now, a large study shows that ON 14-24 admissions for self harm, OD, and deaths for same decreased by 20% to mid '21.
Science is not performed by press release. Science is not performed by large bold numbers presented without any historical context.

Science is performed by rigorous presentation analysis scrutiny and peer review of data.

Shame on everyone involved with this debacle.
I cannot express my gratitude enough to the authors who did the hard work to present this data and to get it published.
