Box plots show unadjusted disease-specific function to 10 years. Crossbars are medians; boxes, IQRs; whiskers extend to the furthest points within 1.5 × IQR; dots, more extreme values with intensity signifying relative number of participants. Curves show adjusted mean EPIC-26 scores starting at unadjusted mean baseline for time zero.
