Table 2 Multivariable adjusted hazard ratio for each of the study outcomes stratified by quartile of serum uric acid concentration

From: Hyperuricemia and untreated gout are poor prognostic markers among those with a recent acute myocardial infarction

  Hazard ratio (95% CI)

  1. aP < 0.001 in comparison to the first quartile; bP < 0.01. in comparison to first quartile; cTrend test performed using serum urate as a continuous variable. The covariates adjusted for in this regression included: age, gender, African-American ethnicity, body mass index, blood pressure/hypertension, smoking, diabetes status, physical activity measure, hyperlipidemia, hypertriglyceridemia, renal function, and other non-steroidal anti-inflammatory drug use.
  2. CHD, coronary heart disease; CI, confidence interval; N, number.
