Distribution of hypoglycemia and control labels across the training, validation, and test sets

# (%) Hypoglycemic # (%) Control
Training output 181,705 (4.43%) 3,915,364 (95.57%)
Validation output 44,866 (4.32%) 993,671 (95.68%)
Test output 57,181 (4.43%) 1,233,467 (95.57%)

Labels were generated at 4-hour intervals based on whether a hypoglycemic event (BG < 70 mg/dL) occurred within the subsequent 24 h.
