Study (reference) | Summary of results | Statistics as provided by the article |
---|---|---|
Araki et al. (20) | Higher potassium is beneficial; highest quartile had lowest all-cause mortality | HR (95% CI): 0.71 (0.56, 0.90) |
He et al. (23) | Neutral; not associated with all-cause mortality; 95% CI across all quartiles crossed 1 | HR (95% CI) Q4 vs. Q1: 0.89 (0.64, 1.23) |
Leonberg-Yoo et al. (25) | Lower potassium is harmful; all-cause mortality average follow-up 19.2 y (10.8–20.6 y); lower quartiles higher risk for mortality | HR (95% CI) Q1 vs. Q4: 1.71 (1.23, 2.38) |
Nagata et al. (28) | Moderate potassium is beneficial; death—comparing reference category of <1.5 g to 2.0–2.5 g and 2.5–3 g, lowest risk in higher quintiles | HR (95% CI): 0.36 (0.19, 0.70) |
