And one IQR increment in CRP (1.74 ng/mL) was associated with decreases of 11.00% (95% CI: −16.95% to −4.61%, p = 0.001) in SDNN, decreases of 8.09% (95% CI: −14.65% to −1.03%, p = 0.027) in r-MSSD, decreases of 22.67% (95% CI: −35.48% to −7.32%, p = 0.006) in LF, decreases of 22.98% (95% CI: −37.14% to −5.63%, p = 0.012) in HF, and decreases of 16.54% (95% CI: −28.47% to −2.61%, p = 0.021) in TP, respectively (Fig. 2B). The gene discussed is CRP; the disease is hydrops fetalis.
