RNASEL and Abdominal obesity: The subjects with central obesity (16.9 ± 6.6 vs. 18.9 ± 8.4 μg/ml, P = 0.011), elevated BP (16.6 ± 6.9 vs. 18.6 ± 7.9 μg/ml, P = 0.015) and IFG (16.1 ± 6.5 vs. 18.5 ± 7.9 μg/ml, P = 0.003) respectively had lower serum RNase-L concentrations than those without (Fig. 1).
