Table 4 Multivariate-adjusted odds ratios (95% confidence interval) for abnormal heart rate recovery (HRR) by quartile of log C-reactive protein (log CRP) and white blood cells (WBCs) count

From: Relationship between heart rate recovery and inflammatory markers in patients with polycystic ovary syndrome: a cross-sectional study

Variable Quartile 1 (Reference) Quartile 2 Quartile 3 Quartile 4
logCRP (mg/dl) (n = 67) ≤0.8 (n = 75) 0.81–1.19 (n = 53) 1.2–1.5 (n = 48) ≥1.5
   Crude model 1.00 1.44 (1.21–1.86) 2.23 (1.73–2.88) 3.41 (2.42–4.25)
   Adjusted model 1.00 1.19 (0.81–1.63) 1.34 (0.93–1.99) 1.59 (1.07–2.33)
WBCs count (× 109 cells/l) (n = 62) ≤5.0 (n = 71) 5.1–6.0 (n = 58) 6.1–7.0 (n = 52) ≥7.1
   Crude model 1.00 1.41 (1.14–1.93) 1.95 (1.48–2.65) 2.77 (2.19–3.58)
   Adjusted model 1.00 1.38 (1.06–2.12) 1.33 (0.97–1.96) 1.61 (1.14–2.46)
  1. Crude model is unadjusted. Adjusted model includes age, BMI, TC, HDL-C, TG, fasting glucose, AUCINS, HRREST, and VO2peak.
  2. Abbreviations: AUCINS, area under the curve for insulin; BMI, body mass index; CRP, C-reactive protein; HDL-C, high density lipoprotein cholesterol; logCRP, logarithmic transformation of CRP values; HRREST, resting heart rate; TC, total cholesterol; TG, triglycerides; VO2max, maximal oxygen consumption; WBCs, white blood cells.
