NPPB and stroke disorder: The optimal cutoff points for NT‐ProBNP,d‐dimer, and LAD levels to distinguish the NVAF group from the NVAF with stroke group were 715.0 pg/ml, 0.515 ng/ml, and 38.5 mm, respectively, with the area under the curve (AUC) being [0.801 (95% CI: 0.76–0.84); 0.770 (95% CI: 0.72–0.85); 0.752 (95% CI: 0.71–0.80), p < .01].
