The overall in-hospital mortality was 8% in one research setting. For patients with qSOFA scores less than 2, the mortality rate was 3% (95% CI, 2%-5%) vs 24% (95% CI, 18%-30%) for patients with a qSOFA score of 2 or higher (absolute difference, 21%; 95% CI, 15%-26%).

At the 95% confidence level, the mortality rate margin of error for patients with a qSOFA score of less than two is 2.5%; the mortality rate margin of error for patients with a qSOFA score of two or higher is 6%.

Question: Comparing the 95% confidence intervals for the two patient groups, which interval estimate is more precise?
