Sensitivity analyses were performed using multiple tests, and the test for heterogeneity showed that the effects of the 4 candidate genes on CHD showed no heterogeneity, whereas eqtl-a-ASG00000115415 (signal transducer and activator of transcription 1 [STAT1]) had a P-value of 0.000, and the results were still satisfactory using the IVW test for random effects (Table 2). Here, STAT1 is linked to coronary artery disorder.
