Xiao'er Fengreqing oral liquid versus Xiao'er Yanbian granules for pediatric acute pharyngitis/tonsillitis (external wind heat syndrome): protocol and statistical analysis plan for a multi-center, randomized, double-blind, active drug-controlled trial.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate the effectiveness and safety of Xiao'er Fengreqing Oral Liquid (XFOL) for pediatric acute pharyngitis/tonsillitis (external wind heat syndrome) through a multi-center, randomized, double-blind, positive-controlled, non-inferiority clinical trial. Method: A total of 120 participants (60 per group) will be randomized to receive either XFOL or Xiao'er Yanbian Granules (positive control) for 5 days. The primary outcome is the throat pain resolution rate and overall effective rate at Day 5, assessed via the Wong-Baker Faces Pain Rating Scale (WBS). Secondary outcomes include time to symptom onset/resolution, fever resolution time, and traditional Chinese medicine (TCM) syndrome scores. Safety assessments will monitor adverse events, vital signs, and laboratory parameters. Statistical analyses will follow a pre-specified plan, employing non-inferiority testing, survival analysis for time-to-event endpoints, and generalized estimating equations for repeated measures. Missing data will be handled using the last observation carried forward (LOCF) method for effectiveness endpoints, while safety analyses will rely on observed cases. Conclusion: This trial will provide rigorous evidence on the non-inferiority and safety profile of Fengreqing Oral Liquid, supporting its integration into pediatric care for acute upper respiratory infections. Adherence to a predefined statistical analysis plan ensures transparency and minimizes bias, ultimately guiding evidence-based clinical practice for TCM interventions.
