Model 1. Impact of hospitalization variables on the prediction of post-stroke depression category before (1a) and after (1b) taking into account the baseline level of tobacco dependence. Model 2. Impact three months follow-up variables on post-stroke depression category before (2a) and after (2b) taking into account the level of tobacco dependence.
