We present a comparative study between headache clinic populations from 2 inherently different regions of the United States. Using standardized methods, 1 of us (JFR) prospectively evaluated 578 new patients attending the headache clinic at the University of California in San Diego. In a similar manner, we subsequently evaluated 115 new patients presenting to the headache clinic at the University of South Alabama in Mobile, Alabama. We found few differences between the 2 populations. These differences more likely reflect regional variations in healthcare delivery or methodologic artifact than intrinsic dissimilarities.
我们对来自美国两个本质上不同地区的头痛门诊患者群体进行了一项对比研究。我们中的一人（JFR）采用标准化方法，对在圣地亚哥加利福尼亚大学头痛门诊就诊的578名新患者进行了前瞻性评估。随后，我们以类似方式对在阿拉巴马州莫比尔市南阿拉巴马大学头痛门诊就诊的115名新患者进行了评估。我们发现这两个群体之间几乎没有差异。这些差异更可能反映的是医疗服务提供方面的区域差异或方法学假象，而非内在差异。
