The low-dose UTI group significantly suppressed IL-6 levels (T4: −0.35 [−0.57, −0.13] P = 0.003; T5: −0.35 [−0.57, −0.13] P = 0.003), with the high-dose group showing more pronounced inhibition (T4: −0.78 [−1.00, −0.56] P < 0.001; T5: −1.24 [−1.46, −1.02] P < 0.001), demonstrating a dose-dependent effect. Here, IL6 is linked to bacterial urinary tract infection.
