Crude likelihood ratios (LR) for the predictors of each febrile illness (bivariate analysis).

Only results for which the LR+ was 2 and above or the LR- was 0.5 and below are provided (otherwise the cell is left empty; if not applicable, NA is mentioned). LR with a 95% confidence interval (CI) that did not include 1 are in bold.仅保留阳性似然比（positive likelihood ratio, LR+）≥2 或阴性似然比（negative likelihood ratio, LR-）≤0.5 的结果（其余情况单元格留空；若不适用，则标注NA）。当似然比（likelihood ratio, LR）的95%置信区间（confidence interval, CI）未包含1时，将对应结果以粗体标注。
