CRP and digestive system disorder: When putting potential covariates (marital status, education level, residential area, smoking status, alcohol consumption, physical activities, CRP, triglycerides, heart problems, stroke, digestive disease, psychiatric problems, rheumatism) into logistic regression models, we observed that the associations of low ASM mass (OR = 1.79, 95% CI = 1.51 ~ 2.11, p < 0.001), low PEFR (OR = 2.76, 95% CI = 2.14 ~ 3.55, p < 0.001), and probable RS (OR = 2.18, 95% CI = 1.84 ~ 2.58, p < 0.001) with an increased prevalence of CLDs remained significant (Table 2).
