Peri-colonoscopy hypoglycaemia in type 2 diabetes: Temporal patterns and asymptomatic presentation

Figure 1 Temporal distribution of hypoglycaemic events and identification of dual high-risk windows during the peri-colonoscopy period. Blue bars indicate incidence rates (left Y-axis); orange bars indicate asymptomatic proportions (right Y-axis). The two Y-axes represent different metrics and should not be interpreted as implying a direct quantitative relationship. Two high-risk windows are highlighted: (1) Early bowel preparation window (20:00-06:00) (highest asymptomatic proportion, 70.5%); and (2) Immediate post-colonoscopy (highest incidence rate, 6.93). pt-h: Patient-hours.
