Notes:

- The estimates and diagnostic values in this table correspond to pancreatic cancer PheRS constructed in MGI using association estimates obtained from time-restricted co-occurrence analysis in the matched MGI discovery cohort.

- The odds ratio, corresponding 95% confidence interval estimate, and p-value come from a logistic GLM model for the PheRS on pancreatic cancer, adjusted for, sex, birthyear, genotyping array, and the first four principal components of the genotype data.

- The AUC and corresponding 95% confidence interval are from an unadjusted ROC model.

- The Hosmer-Lemeshow test statistic and p-value and the Brier score are from a matched, unadjusted logistic GLM model for pancreatic cancer case/control status.

- The percentile-based odds ratios and confidence intervals come from a Firth-corrected logistic regression model on pancreatic cancer case/control status adjusted for sex, age at time threshold, genotyping array, and the first four principal components of the genotype data.
