95% Confidence intervals are calculated using the robust sandwich estimate of Lin and Wei [54] for the covariance and standard error. P-values are Wald p-values from the conditional logistic model using the robust sandwich estimate. Covariates that reached the statistical significance level p≤0.1 are included in this table.
