*CONTEXT* Dynamic prediction models provide predicted probabilities that can be updated over time as data become available. There is growing interest in the use of #machinelearning 🤖; yet, their use in the context of dynamic survival #prediction has been limited.
2/n
*FINDINGS* The proposed #ML approach showed similar cross‐validated predictive performance to
standard landmarking approaches but greater than joint modelling 4/n

*CONTEXT* Standard network meta‐analysis & indirect comparisons combine aggregate data from multiple studies, assuming that any effect modifiers are balanced across pops. & often incurring in aggregation bias 2/n
*AIM* Propose a new method extending the standard network meta‐analysis framework
*METHOD* Use of general numerical approach using quasi‐Monte‐Carlo integration 3/n
*CONTEXT* Quantifying hidden populations such as victims of modern slavery is challenging; yet, needed to develop strategies leading to legislation, inc. the Modern Slavery Act 2015 2/n
*AIM* Investigate the stability and robustness of various multiple‐systems‐estimate methods to measure modern slavery using Kosovo 🇽🇰as case study
*METHOD* Use of multiple‐systems‐estimate methods to develop a new Markov chain Monte Carlo #Bayesian approach
