When considering clinical examination findings, the likelihood for heart failure diagnosis decreased for high jugular venous pressure (RRR, 0.49; CI 95%, 0.32–0.76), pleural effusion (RRR, 0.35; CI 95%, 0.23–0.54), hearing third heart sound, (RRR, 0.50; CI 95%, 0.33–0.77), heart murmur (RRR, 0.57; CI 95%, 0.37–0.88), troponin levels (RRR, 0.59; CI 95%, 0.38–0.91), and NTproBNP levels (RRR, 0.36; CI 95%, 0.24–0.56). This evidence concerns the gene NPPB and Pleural effusion.
