CRP and cardiovascular disorder: However, a subgroup analysis categorising CRP levels according to risk of cardiovascular disease: < 1μg/ml (low risk), 1–2.9μg/ml (moderate risk), and ≥ 3μg/ml (higher risk) [31, 32], revealed a significant 28.3% decline in CRP levels following treatment in the nine participants in the high-risk group compared with V1 (p < 0.0195; Table 2).
