Trial Outcomes & Findings for Metformin as a Novel Therapy for Autosomal Dominant Polycystic Kidney Disease (NCT NCT02656017)

NCT ID: NCT02656017

Last Updated: 2022-08-09

Results Overview

GSRS is a widely used, validated 15-item questionnaire used to assess GI symptom burden (minimum, maximum: 1, 7, where higher mean score is worse outcome). Mean change to 24 months, estimated with a repeated measures analysis (baseline, 2 weeks, 6 weeks, 1 month, 3 months and every 3 months thereafter to 24 months) using a linear mixed model.
