Our simple-to-use nomogram established for predicting OSA. The nomogram was developed in the training group by incorporating the following eight parameters: age (years), sex (0 = male; 1 = female), glucose (mmol/L), ApoB (g/L), insulin (μU/mL), BMI (kg/m2), NC (cm), and WC (cm). OSA, obstructive sleep apnea; ApoB, apolipoprotein B; NC, neck circumference; WC, waist circumference; BMI, body mass index
