Although moderate positive correlations were observed between GDF15 and PCT (r = 0.49451) and Neu (r = 0.53297), these associations did not reach statistical significance ( p = 0.08582 and p = 0.06074, respectively).
Similarly, creatinine levels started to show a decreasing trend from Day 2 and were significantly lower than Day 1 on Day 6 and subsequent days ( p < 0.05) ( Figure 3 B). eGFR values increased significantly from Day 5 compared to Day 1 ( p < 0.05), indicating a recovery process in glomerular function following the acute phase of sepsis ( Figure 3 C). 3.3.
