1. Yuye Jiedu Granules are composed of jade leaf golden flower, mountain silver flower, chrysanthemum, wild chrysanthemum, wild plum, mountain sesame and centella. It has the effects of clearing heat and detoxification, relieving the surface, clearing heat and dampness, promoting body fluid and throat. It is mainly used for colds and coughs caused by exogenous wind-heat, pharyngitis, dry mouth, sore throat, short urine, and prevention of heat stroke;
2. Using positive drug control, propensity score matching method, and multi-center clinical trial design:
(1) Control: The positive drug is oseltamivir phosphate granules;
(2) Sample size: According to relevant literature, the 7-day recovery rate of oseltamivir is about 90%, and the non-inferior value is 0.12, α is 0.025, β is 0.2, and the estimated sample size is 99 cases per group. Take the test group For the matching benchmark, according to 1:1 matching, considering the matching failure and dropout, it was finally decided to include 340 cases, including 135 cases in the experimental group and 205 cases in the control group.
(3) Propensity score matching: Intervention measures (grouping situation) are used as dependent variables, and center/professional, age, ethnicity, weight, height, course of disease, past history, pre-diagnosis drug combination, and baseline CARIFS score are used as covariates. Logistic regression was used to calculate the propensity score value, using the caliper matching method, the caliper value was set to 20% of the standard deviation of the propensity score, and the two groups of patients were matched at a 1:1 ratio based on the test group.
(4) Multi-center: This trial was jointly completed by multiple centers. Subjects enrolled in the Pediatric Department of General Hospital took Oseltamivir Phosphate Granules, and subjects enrolled in the Department of Traditional Chinese Medicine and Traditional Chinese Medicine Hospital of General Hospital took Yuye Jiedu Granules.
