Numbers in bold indicate significant results. n of all analyses = 102. B = parameter estimate of being in the IG for the difference T1-T0 or T2-T0, CI = confidence interval, SD = standard deviation, CAU = care-as-usual, IG = intervention group, OR odds ratio for improvement in the IG compared to CAU between baseline and T1 or T2. 1 AAHLS questionnaire: scores from 10 to 30 with higher scores representing better health literacy. 2 eGFR = estimated glomerular filtration rate in ml/min/1.73m2; results of T1 not reported because they were not reliable (missing not at random); intervention effect T0-T2 is not corrected for eGFR.
