Technical Verification and Assessment of Independent Validation of Biomarker Models for Endometriosis

Table 3

Correlation analysis of biomarker measurements of the technical verification study (n = 136) versus the study performed by Vodolazkaia et al. [11].

Biomarkers	Spearman r	95% CI
CA-125	0.97	0.96-0.98
VEGF	0.42	0.27-0.55
Annexin V	0.72	0.63-0.80
Glycodelin	0.63	0.51-0.73
sICAM-1	0.51	0.37-0.63

r between 0 and 0.30 is interpreted as negligible correlation, 0.30 and 0.50 as low correlation, 0.50 and 0.70 as moderate correlation, 0.70 and 0.90 as high correlation, and 0.90 and 1.0 as very high correlation [23]
