Results
Fifty-seven patients were enrolled in the study and randomly assigned to VLCKD (n = 29) or HBD (n = 28). Four patients (13.8%) discontinued the study in VLCKD group, whereas fourteen patients (50%) dropped out in HBD group. We explored potential deviations as attrition bias using a sensitivity analysis, and attrition bias was not observed. In fact, when comparing the group that completed the study and the drop-out group, no statistically significant differences emerged, except for the SF36 RP.
