Lognormal AFT survival curves for silico-tuberculosis and TB without silicosis groups (n = 2742). The lognormal-based predicted survival curves with silico-tuberculosis as the predictor in the model depict survival probabilities for two groups: TB without silicosis and silico-tuberculosis. The X-axis represents time in months, and the Y-axis represents the survival probability. The green curve represents the survival probability for the TB without silicosis group, while the orange curve represents the silico-tuberculosis group. The unadjusted predicted median survival time was substantially lower for the silico-tuberculosis group (78 months) compared to the TB without silicosis group (264 months), underscoring the significant survival disadvantage faced by silico-tuberculosis patients.
