Clinical characteristics of Chinese subjects categorized by serum CRP levels (n = 112).
| Low CRPa | High CRPa | P value | |
|---|---|---|---|
| CRP (pg/mL)b | 154.4 ± 111.1 | 839.5 ± 353.8 | <0.001 |
| Age (years) | 59.7 ± 6.9 | 60.0 ± 8.8 | 0.77 |
| Waist circumference (cm) | 80.9 ± 8.8 | 83.7 ± 10.0 | 0.19 |
| Systolic BP (mmHg) | 121.0 ± 17.0 | 134.0 ± 8.2 | <0.001 |
| Diastolic BP (mmHg) | 71.9 ± 23.3 | 75.2 ± 10.9 | 0.08 |
| Triglycerides (mmol/L) | 1.2 ± 0.5 | 1.7 ± 1.1 | 0.01 |
| HDL-C (mmol/L) | 1.6 ± 0.4 | 1.4 ± 0.4 | 0.001 |
| Fasting plasma glucose (mmol/L) | 5.2 ± 0.9 | 5.5 ± 1.2 | 0.38 |
| Irisin (μg/mL)b,c | 8.5 (5.8, 11.7) | 6.5 (3.6, 10.0) | 0.05 |
aSerum CRP levels were categorized into low and high levels based on sample median. bStatistical analyses carried out on available data. cOutliers were excluded. Data were mean ± SD or median (25th, 75th) for serum irisin level. BP: blood pressure; CRP: C-reactive protein; HDL-C: high-density lipoprotein cholesterol.
