NPPB and diabetes mellitus: The risk predictors identified by OR > 1 were carotid artery disease (a strong risk factor, OR = 9.53, p = 0.0106); diabetes mellitus, associated with increased risk (OR = 5.47, p = 0.0095); history of stroke/TIA, associated with increased risk (OR = 5.99, p = 0.0349); and elevated NT-proBNP, associated with a modest but statistically significant increase in risk (OR = 1.0023, p = 0.0028), Table 3.
