CRP and systemic inflammatory response syndrome: However, no statistically significant differences were observed in other clinical outcomes, such as CRP levels at 72 h (SMD: −4.92; 95% CI: −17.67 to 7.83; p = 0.13), the duration of hospital stay (SMD: −0.89; 95% CI: −2.26 to 0.48; p = 0.23), or the incidence of systemic inflammatory response syndrome at 24, 48, and 72 h after the start of fluid therapy.
