Data are exponential of regression coefficients (95% confidence interval), which indicates fold change in the outcome variable of interest by one interquartile increase in the corresponding covariate.

CI=confidence interval, QSART=quantitative sudomotor axon reflex test, UENS=Utah Early Neuropathy Scale, VAS=visual analog scale, NRTI=nucleoside reverse transcriptase inhibitor
