Table 4 Odds ratios and 95% confidence intervals for cardioembolic stroke classification, relative to Af, mitral regurgitation, plasma BNP, and LA dimension.

From: Plasma brain natriuretic peptide as a surrogate marker for cardioembolic stroke

  1. The multivariate odds ratios are determined from logistic regressions including all four variables (Χ2 = 127.5, p < 0.001). Plasma BNP was independent predictor of cardioembolic stroke, even after controlling Af, mitral regurgitation, and LA dimension.
  2. *: p < 0.05; **: p < 0.01.
