PERIPHERAL NEUROPATHY
Ethnicity was missing for 59 (2%) study participants and BMI was missing for 45 (2%). No missing data were reported for other patient and clinical factors. However, severe missing data were reported for peripheral neuropathy. At baseline, peripheral neuropathy scores were missing for 1147 (40%) study participants. This was increasing over time, and was 44%, 46%, 57%, 54%, 56%, 70%, 51%, and 50% at month 1 to month 12. Missing data reached 88% at both 18-month and 24-month peripheral neuropathy assessments. This is represented by wide CIs in the analysis and indicates that the results, especially for the last two time points, should be interpreted with caution.
