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
Background: Sanfeng Tongqiao Diwan has shown the potential to alleviate acute, recurrent, and chronic rhinitis in adults based on available studies. However, the evidence for its application in upper airway cough syndrome (UACS) is unclear. The purpose of this study was thus to investigate the efficacy and safety of Sanfeng Tongqiao Diwan in the treatment of UACS. Methods: This was a single-center, randomized, double-blind, placebo-controlled clinical trial. A total of 60 patients who satisfied the inclusion criteria were randomly divided into experimental and placebo groups in a 1:1 ratio. The experimental group was given Sanfeng Tongqiao Diwan, and the placebo group was given a simulant for 14 consecutive days. The follow-up period was 15 days. The primary outcome was the total effective rate. The secondary outcomes included clinical efficacy, Visual Analogue Scale (VAS) of related symptoms, and Leicester Cough Questionnaire in Mandarin-Chinese (LCQ-MC) scores before and after the treatment. Additionally, the safety was also evaluated. Results: The total effective rate in the experimental group was 86.6% (26/30), which was significantly higher than the 7.1% (2/28) in the placebo group (difference 79.6; 95% CI: 57.0 to 89.1; P<0.001). Nasal congestion, runny nose, cough, postnasal drip, and overall symptoms in the experimental group were significantly lower than those in the placebo group after treatment (3.7±1.5 Conclusions: Sanfeng Tongqiao Diwan improved the symptoms and living quality of patients with UACS and showed acceptable safety. The results of this trial represent rigorous clinical evidence for the application of Sanfeng Tongqiao Diwan and further support a new option in UACS treatment.
