PRL and cervical squamous intraepithelial neoplasia: Table 5 presents a summary of the association of CIN with RFs and the graphic OR of the RF association with CIN (Figure 4) based on the univariate analysis, whereas Table 6 presents a summary of the multivariate binary logistic regression of the RFs associated with CIN, where PRL based on GFR <60 ml/min resulted as the most important independent RF for CIN (p = 0.039, OR 1.52, CI 95%: 1.02-2.2).
