4.3 Inflammatory dynamics IL−6 was significantly elevated in non−survivors throughout the 21−day period, and its trajectory exhibited a highly significant time−by−status interaction ( P = 0.003).

In multivariable Cox analysis adjusting for age, NRS2002, Burn Index, and the five most significant biomarkers from univariable analysis (NK cells, TRF, CD4/CD8 ratio, NB, and PA), none of the biomarkers retained independent prognostic significance, although NK cells showed a trend toward protection (HR = 0.97, P = 0.097) ( Table 4 ).
The strong protective association of NK cells in univariable analysis (HR = 0.95, P < 0.001) and its trend toward significance in multivariable modeling (HR = 0.97, P = 0.097) highlight the importance of innate immune competence.
