*Main analysis: Assumes albumin was ≥3.5 g/dL for those without documented albumin levels.
†Sensitivity analysis: Patients with undocumented albumin who did not meet the high-risk criteria based on their other characteristics were excluded, leaving 521 of the 625 in this analysis.
‡Comparisons between the two groups were evaluated using the two-sided χ2 test or Fisher’s exact test, ignoring the unknown category.
