84 Chapter 5 Supplement 1 The table below shows the analysis of the subgroups pTRG1-3 versus pTRG4-5 and expert readers versus non-expert readers using a multilevel logistic regression model. Table S1 Log Odds ratio, confidence intervals and p-values of the multilevel logistic regression model Understaged (ymrT < ypT) Correct (ymrT = ypT) Overstaged (ymrT > ypT) pTRG1-3 vs pTRG4-5* Estimates(95%CI) + p-value -1.0(-2.3;0.3) p=0.11 -1.0(-1.7;-0.2) p=0.01 2.7(1.0;4.4) p=0.002 Expert vs non-expert* Estimates(95%CI) + p-value -1.0(-1.4;-.65) p=4.2e-08 0.28(0.03;0.52) p=0.02 0.4(0.1;0.7) p=0.009 * reference category for the multilevel logistic regression model
