IL10 and metabolic syndrome: As shown in Figure 5A, in the results of univariate factor analysis, elevated pro-inflammatory factors and dyslipidemia were significantly and positively associated with hospitalization duration, whereas the anti-inflammatory factors IL-10 and HDL were significantly and negatively associated with hospitalization duration, suggesting that both enhanced inflammatory response and dyslipidemia (especially high TG, LDL and low HDL) may extend the duration of hospitalization.
