Stratified analysis of the age-related waist circumference cut-off model for the screening of dysglycemia at zero-cost

•Novel artificial intelligence methods can simplify the screening of dysglycemia.•An age-related waist circumference cut-off model to detect dysglycemia.•Stratified analysis in sex, race and glycemia group maintaining good performance.•Good calibration of the model to detect dysglycemia.•Model is ideal to serve as zero-cost large-scale dysglycemia screening tool.
