Liver and kidney volumes are height adjusted and log transformed. ADPKD: autosomal dominant polycystic kidney disease; PLD-Q: polycystic liver disease questionnaire; eGFR: estimated glomerular filtration rate using the Modification of Diet in Renal Disease formula; htKV: height-corrected kidney volume, htLV: height-corrected liver volume; CI: confidence interval.
