Meta-analyses Pearson’s r correlations. Meta-analysis of 4/31 identified EC markers fulfilling the inclusion criteria for meta-analysis. Overview of overall Pearson’s correlations (r, with 95% CI) between SLE disease activity and serum/plasma levels of each included EC marker. n = total number of SLE patients from all articles per EC marker. In the Forest Plot, significant correlations (95% CI does not include ‘0’ and p < 0.05) are indicated by black text and filled diamonds (♦) and non-significant correlations (95% CI includes ‘0’ and p > 0.05) are indicated by grey text and open diamonds (♢) Calculated p-values are based on Fisher's Z Transformation
