IL7R and chronic obstructive pulmonary disease: In parallel analysis of our COPD cohort using precision–recall curves, we found the latitude (AUC = 0.89, associated criterion ≤ 25.06), longitude (AUC = 0.93, associated criterion ≤ 121.80), SO2 (AUC = 0.95, associated criterion ≥ 2.14), THC (AUC = 0.94, associated criterion ≥ 2.14), PM2.5 (AUC = 0.95, associated criterion ≥ 16.24), PM10 (AUC = 0.95, associated criterion ≥ 16.24), BMI (AUC = 0.95, associated criterion ≤ 29.36), and lnc-IL7R (AUC = 0.91, associated criterion ≤ 1.23) excellently stratified patients into COPD-E and non-COPD-E groups (Figure 4C–G).
