Logistic regression analysis of rodent-related and environmental characteristics associated with Leptospira transmission and scoring system at household level.

aOdds ratios (OR) and 95% confidence intervals (CI) are shown for analyses. Logistic regression was performed to obtain estimates for odds ratios which were adjusted for covariates in the final model.bAssignment of points to risk factors was based on a linear transformation of the corresponding β regression coefficient. The coefficient of each variable was divided by 0.90 (the lowest β value, corresponding to Un-plastered walls), multiplied by two, and rounded to the nearest integer.cWalls composed of exposed bricks without external application of stucco or plastering.Logistic regression analysis of rodent-related and environmental characteristics associated with Leptospira transmission and scoring system at household level.

a. 本分析展示了比值比（odds ratios, OR）与95%置信区间（confidence intervals, CI）。为获得比值比的估计值，研究采用逻辑回归（logistic regression）分析，并在最终模型中对协变量进行了校正。
b. 风险因素的分值赋值基于对应β回归系数的线性变换：将每个变量的系数除以0.90（该值为最低β值，对应未抹灰墙面），再乘以2，随后四舍五入至最接近的整数。
c. 墙面由裸露砖块构成，未在外表面涂抹灰泥或抹灰。
本研究针对家庭层面与钩端螺旋体（Leptospira）传播相关的啮齿动物相关特征、环境特征及评分系统开展逻辑回归分析。
