Nomogram of the EGFR mutation predictive model. The predictors are arranged based on their effect size. Asterisks refer to the levels of statistical significance: *p < 0.05, ***p < 0.001. The square boxes show the distribution of the data. The points for each predictor are observed by drawing a perpendicular line towards the points bar at the top of the nomogram, and are summed to obtain a total score. The estimated probability of mutation positivity is provided in correspondence to the total score
