CRP and tuberculosis: We hypothesized that (i) higher TRIAD-TB scores would associate with greater 30-day mortality and longer length of stay; (ii) TRIAD-TB would outperform domain-specific comparators built from physiology-only (SpO2, RR), inflammation-only (CRP, SII), or nutrition-only (BMI, albumin) inputs; and (iii) incorporating 72 h deltas would add incremental discrimination beyond baseline values alone.
