ADRB1 and Stroke: The results revealed that CC (vs GC + GG) of the ADRB1 (1165G > C) gene was associated with stroke occurrence in nondiabetic and noncoronary populations of hypertensive patients (OR: 1.20, 95% CI: 1.03–1.41; OR: 1.30, 95% CI: 1.09–1.56), in hypertensive patients who took BBs (OR: 2.43, 95% CI: 1.08–5.47; OR: 1.17, 95% CI: 1.010–1.348) or diuretics (OR: 1.707, 95% CI: 1.226–2.376) (Figure 2).
