165 PARTICIPANT BACKGROUND Baseline characteristics in the two groups were similar (table 5.1). Patients in the control group more often had severe CKD (p=0.004) and their mean eGFR was lower (p=0.001) compared to the intervention group. 64.2 percent of the patients in the intervention group had LHL, comparable to the 75.8 percent in care-asusual. For smoking and alcohol intake, baseline measures indicated a healthy sample, compared to the general Dutch population (see supplementary file 1).

One participant did not complete T1, but filled in T0 and T2. Figure 5.1a Flow chart presenting enrollment, allocation, follow-up and analysis of the patients in our study
