GCG and congenital bilateral aplasia of vas deferens from CFTR mutation: When the GLP-1 quartile (median = 12.31 pmol/L, 25th−75th percentiles 8.68–16.73 pmol/L; range 0.05–39.37 pmol/L) in the Non-CAVD and CAVD groups was included in Model 2 (baseline characteristics of the Non-CAVD and CAVD groups according to GLP-1 level, see Supplementary Table 2), the association between age, fasting glucose, HbA1c, HDL, BUN, and CAVD remained significant.
