ADPKD, autosomal dominant polycystic kidney disease; ADPLD, autosomal dominant polycystic liver disease; hTLV, height‐adjusted total liver volume; IUD, intrauterine device; Ln, natural logarithm; TLV, total liver volume. Plus–minus values are means ± SD.
aNonparametric values expressed as median (interquartile range (IQR)). bSeverity classification is based on hTLV (mL/m).
