Results of meta-analysis
There were significant differences in serum resistin levels between CD
patients and healthy controls, and CD patients had higher resistin
concentrations (SMD = 1.76, 95% CI = 0.64 to 2.88, p = 0.002).
Meanwhile, serum resistin levels in UC patients were also higher than
that in
healthy
controls (SMD = 2.10, 95% CI = 1.03 to 3.17, p < 0.001
) (Figure 2). In addition, subgroup analyses stratified by region showed
that resistin levels of CD or UC patients had differences in Europe when
compared with healthy controls, whereas no significant differences were
found in non-Europe (Figure 3). Meta-regression analysis was applied for
detecting additional sources of heterogeneity, indicated that
publication year may be a source of heterogeneity across studies (Table
2).
