Examples of predicted probabilities of anxiety at baseline.
<p>(*)The possible range of the SF-12 is 0–100. High scores indicate good health/well-being. Mean (Standard Deviation) Short Form 12 (SF-12) mental and physical subscale scores for Spain are 47.1 (12.4) and 43.8 (11.4), respectively <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0106370#pone.0106370-Belln3" target="_blank">[39]</a>.</p><p>Examples of predicted probabilities of anxiety at baseline.</p

Model to predict drop-out.
<p>(*) Multi-level logistic regression with health center as a random component. We selected variables included in the final model from the 39 measured in this study using a threshold for inclusion of p<0.20 in bivariate regression. From the model thus obtained, those variables with p>0.05 were extracted step by step to obtain a more parsimonious model.</p><p>Model to predict drop-out.</p
