Long-Term Clinical Consequences of Severe Oral Mucositis in Survivors of Lip, Oral Cavity, and Pharynx Cancer Versus Leukemia: A Propensity-Score-Matched Comparative Cohort Study Using Real-World Data.

The final matched cohorts ( n = 8362 for CLOP cancer and n = 5016 for leukemia) yielded extremely high statistical power (>99%) to detect the observed hazard ratios (e.g., HR 1.94 for mortality in CLOP cancer) with narrow confidence intervals, as evidenced by the highly significant p values and precise estimates reported.
