Linear regression model. ISTAPS study
SE: standard error
Predictors variables were measured at baseline
Final models were adjusted only for significant variables.
^*p ≤ 0.05 ^**p ≤ 0.01 ^***p ≤ 0.001
^† The standard errors were adjusted for the cluster effect of the Basic Care Unit
^‡ Linear mixed-effects model
