Table 2.

Median time to events for included very-early onset (VEO) and non-VEO patients with autosomal dominant polycystic kidney disease. N/A = the median estimate could not be calculated because the failure probability never exceeded 0.5. Hazard ratios and p-values are for unadjusted Cox proportional hazards analysis comparing VEO to non-VEO.
