Table 2 Pooled estimates of the regression coefficients \( \hat{\beta_k,} \) ORs and the 95% CrIs for each one of the parameters in the model (centralized to the mean), using Rubin’s rules. The estimated σ (standard deviation of the impact of the variables on multiple observations for the same individuals) is 0.01. The estimated correlation ρ between the effects of the variables is 0.49. The pooled optimism-corrected AUC is 0.65 and the pooled optimism-corrected calibration slope is 0.91. Disease duration was transformed to log(disease duration+10), and months since last relapse was transformed to log(months since last relapse+10)
