From: Experience with 2 years’ intervention to progressively reduce salt supply to kitchens in elderly care facilities—challenges and further research: post hoc analysis of the DECIDE-Salt randomized clinical trial

Effects on systolic and diastolic blood pressure of PR versus NR during the 2 years of intervention in DECIDE-salt study. The figure shows the mean and 95%CI of SBP (upper) and DBP (lower) at baseline and each follow-up visit for participants who had their blood pressure measured at each visit. The numbers beside the BP point were mean differences and 95%CI in SBP and DBP at each follow-up visit between comparison groups, which were estimated using a linear mixed model with repeated measurements, accounting for the clustering effect and adjusting for the time of visits as well as time-by-group interaction, among 1219 participants
