Dashed lines indicate the median survival in each environmental risk score (ERS) strata. The estimated adjusted median survival time is 2.47 years (95% CI: 1.84, 3.11) for Quartile 1, 2.12 years (95% CI: 1.68, 2.56) for Quartile 2, 1.99 years (95% CI: 1.61, 2.37) for Quartile 3, and 1.89 years (95% CI: 1.55, 2.22) for Quartile 4. The adjusted survival curves and adjusted median survival time estimates are pooled across all 20 imputed datasets.
