ESR1 and Hypoalbuminemia: In this study, weight loss (OR, 2.827, 95% CI: 1.938–4.926, p = 0.038), hypoalbuminemia (OR, 6.142, 95% CI: 4.129–8.274, p = 0.008), elevated ESR (OR, 4.025, 95% CI: 3.178–6.892, p = 0.016), and increased CRP (OR, 7.539, 95% CI: 5.365–11.723, p = 0.002) were significantly relevant risk factors of the positive finding of VCE [8] (Supplementary Table S3).
