Table 3 Odds ratios for use of each category of psychotropic drugs at one time point given use of the same category of the psychotropic drug at an earlier time point (the distance between time points is called lag), unadjusted and adjusted analyses where relevant covariates adjusted for were measured at the same earlier time
From: Persistent use of psychotropic drugs in nursing home residents in Norway
