We conducted a nested case–control study of 278 cases and 826 matched-controls from the Korean National Health Insurance Service-Health Screening Cohort. Over 11 years before index date (date of PaC diagnosis for cases), all participants had at least one FBG measurement in each of the three time windows: − 11 to − 8, − 7 to − 4, and − 3 to 0 years. Using conditional logistic regression, we estimated odds ratios(ORs) of PaC and 95% confidence intervals (CIs) for hyperglycemia in the overall period and at each interval; for major long-term patterns of FBG across the three intervals (recent-onset, medium-term, and long-standing hyperglycemia).
