An epidemiologic study was done comparing blacks versus whites with regard to the incidence of altered middle ear function or otitis media. Three separate groups were evaluated. All variables were controlled except for race. There appears to be statistically significant less otitis media or altered middle ear function in the black race than the white race.
开展了一项流行病学研究，比较黑人和白人中耳功能改变或中耳炎的发病率。评估了三个不同的组。除种族外，所有变量均得到控制。黑人种族的中耳炎或中耳功能改变在统计学上似乎明显少于白人种族。
