Survival analysis outcomes for the pivotal hub gene, SNAI1, in patients with NSCLC. (A-D) The prognostic significance of SNAI1 in LUAD is depicted through various analytical approaches: A Univariate Cox regression analysis reveals the influence of SNAI1 expression on OS in LUAD; (B) Multivariate Cox regression further substantiates this relationship, adjusting for additional variables; (C) A predictive nomogram, constructed from TCGA datasets, combines SNAI1 levels with other prognostic indicators to estimate survival probabilities in LUAD; (D) The calibration curve associated with the nomogram evaluates the accuracy of survival predictions. (E–H) The prognostic relevance of SNAI1 in LUSC: E Univariate Cox regression analysis assesses the effect of SNAI1 expression on OS in LUSC; (F) Multivariate analysis corroborates these findings, accounting for other prognostic factors; (G) Another nomogram, derived from TCGA data, integrates SNAI1 expression with additional prognostic markers to forecast survival outcomes in LUSC; (H) The corresponding calibration curve assesses the precision of the nomogram’s predictive capability
