Figure 2. Adjusted Survival Curves Stratified by ERS Quartile.

Figure 2.

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.
