Day 8 TnT decrement ≥42% showed a trend toward significance (hazard ratio [HR], 2.2 [95% CI, 0.9–5.0; P =0.067), similar to what was seen in the Kaplan–Meier analysis of this variable (Figure 2 ).
Of note, the median interval from ICI initiation to ICIM admission exhibited a nonsignificant trend toward longer intervals associating with longer survival: a median interval of 28 days (IQR, 20–42) for the short‐term survival group, 42 days (IQR, 30–95) for the intermediate‐term group, and 45 days (IQR, 37–162) for the long‐term group ( P =0.080).
