    Kaplan-Meier survival curves, by Pneumonia Severity Index class and procalcitonin tier. In Pneumonia Severity Index classes I to III, mortality was low, and stratification by procalcitonin tier did not provide additional information. In Pneumonia Severity Index classes IV/V, patients with a procalcitonin level less than 0.1 ng/mL had the lowest 30-day mortality. PCT, Procalcitonin.

In CURB-65 group 1 patients, mortality was low, and stratification by procalcitonin tier did not provide additional information. In CURB-65 groups 2/3, patients with a procalcitonin level less than 0.1 ng/mL had the lowest 30-day mortality.
