Abstract：
We aimed to analyze the association between the average lumbar subcutaneous fat tissue thickness (LSFTT) at each intervertebral level and the presence of hernias in patients with low back pain from an insurance network hospital in Mexico. This observational prospective study included 174 patients with non-traumatic lumbago who underwent magnetic resonance imaging with a 1.5T resonator. Two independent radiologists made the diagnosis, and a third specialist provided a quality vote when needed. The sample size was calculated with a 95% confidence interval using random order selection. Anonymized secondary information was used. Percentages and means with confidence intervals were tabulated. The area under the curve, specificity, and sensitivity of LSFTT were calculated. A regression analysis was performed to analyze the presence of hernias with LSFTT using each intervertebral level as a predictor. The odds of herniation at any intervertebral level increased directly with LSFTT. The average LSFTT predicted the overall presence of hernias; however, the LSFTT at each intervertebral level better predicted hernias for each intervertebral space. The area under the curve for LSFTT in predicting hernias was 68%. In conclusion, the average LSFTT was associated with the overall presence of hernias; patients with more hernias had higher LSFTT values.
摘要：
我们旨在分析墨西哥一家保险网络医院的下背痛患者的平均腰椎皮下脂肪组织厚度（LSFTT）与疝之间的关联。这项观察性前瞻性研究包括174例非创伤性腰痛患者，他们使用1.5T谐振器进行了磁共振成像。两个独立的放射科医生做出了诊断,第三位专家在需要时提供了高质量的投票。使用随机顺序选择以95%置信区间计算样本量。使用匿名的次要信息。列出了具有置信区间的百分比和平均值。曲线下的面积,特异性，计算LSFTT的灵敏度。使用每个椎间水平作为预测因子，进行回归分析以分析LSFTT的疝的存在。LSFTT会直接增加任何椎间水平的疝的几率。平均LSFTT预测了疝气的总体存在；然而，每个椎间水平的LSFTT更好地预测了每个椎间隙的疝。LSFTT预测疝的曲线下面积为68%。总之,平均LSFTT与疝气的总体存在相关;疝气较多的患者LSFTT值较高.
