Just published our study applying a 2-stage model based on individual participant data meta-analysis. We examined patient-specific treatment effects of adding biologics to conventional rheumatoid arthritis treatment.@KChalkou @funada_satoshi @Geointheworld @Toshi_FRKW
Meta-analysis: The benefit of adding biologics to conventional rheumatoid arthritis treatment is uncertain for specific patients, and the interactive application based on a 2-stage model may help with treatment selection in practice. ja.ma/3PB8D4w
A very interesting paper about assessing the performance of treatment benefit of personalised prediction models lead by @oremiou

This recent HTx study, co-authored by experts at @unibern and @CHEyork (@UniOfYork), describes a cross-network meta-analysis (#NMA)/ network meta-regression (#NMR) model that enables cross-design and cross-format synthesis.
Our paper as one of the top Statistics in Medicine downloaded papers for 2021!
Many thanks again to all co-authors for this nice work and great collaboration! @Geointheworld, @amancayork, Fabio Pellegrini @ESteyerberg & @eggersnsf under @HTx_H2020

Friday = free IPD meta-analysis advice day.
I call it frIPDay
(yes, really)
#1 examining treatment-covariate interactions in a 1-stage model is dangerous ... simply including an interaction term merges within-trial & across-trial relationships, which may distort results
ROB-MEN tool is now available! Congrats to all for this amazing tool in NMA

#GHS_Symposium #GHS A perfect presentation by Michael Seo for "Developing prediction models when there are systematically missing predictors on an IPD Meta-analysis"
Our new collaborative work is now published under the #HTx_H2020 umbrella! A prognostic model for relapses in RRMS: development, validation and evaluation of clinical usefulness.
