Psoriasin levels were significantly elevated in both the POS and PostI-UTI cohorts relative to the NEG cohort (p<0.001 for POS vs. NEG; p<0.01 for PostI-UTI vs. NEG) (Fig. 3C), while lactoferrin was elevated in the POS cohort relative to both the PostI-UTI and NEG cohorts (p<0.01 for POS vs. PostI-UTI; p<0.001 for POS vs. NEG) (Fig. 3D).
