A great privilege to have Prof @jonathanasterne at @PainIMPACTNeuRA to talk about assessing risk of bias in randomised trials using the RoB 2 tool.

We're off and away with Summer School 2025! Jonathan Sterne is leading our Advanced causal inference course, ably assisted by tutors Ghazaleh Dashti, Marnie Downes, Daisy Shepherd and Jiaxin Zhang from CEBU. PS. Follow us over on @vicbiostat.bsky.social..

1/ That "immortal time" is so frequent in survival analyses for #causalinference is fascinating. Because "immortal time" doesn't exist in the data, *we* create it when misanalyzing data. Our paper pubmed.ncbi.nlm.nih.gov/39494894/ summarizes why immortal time arises & how to prevent it.

Compared with no invitation for routine PSA testing, a single invitation for a PSA screening test reduced prostate cancer mortality at a median follow-up of 15 years, but the absolute mortality benefit was small. ja.ma/43J43q3 #EAU24
