Efficacy and safety of Qi-Wei-Qing-Yan aerosol in treatment of acute pharyngitis (lung-stomach excess-heat syndrome): study protocol for a randomized controlled trial.
Trial report in Trials, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundAcute pharyngitis accounts for an estimated 15 million patient visits in the United States. However, there is no proven effective and safe treatment. Although Chinese herbal medicine is widely used in the treatment of acute pharyngitis, there is a lack of evidence-based data. Despite several clinical trials conducted in this setting, no randomized placebo-controlled trial has been performed to date. This trial aims to investigate the efficacy and safety of Qi-Wei-Qing-Yan aerosol (QWQYA), a Chinese herbal prescription, compared with a placebo aerosol in the treatment of acute pharyngitis with lung-stomach excess-heat syndrome. METHODS/
designThis is a prospective, multicenter, randomized, double-blinded, parallel-group, placebo-controlled trial. A total of 420 adult patients, of either sex, with acute pharyngitis will be enrolled from seven study sites across China. All patients will be randomly allocated to one of three parallel treatment groups: (1) QWQYA with the current propellant, (2) QWQYA with a previous propellant, and (3) the placebo aerosol with the current propellant. The study medication will be administered into the pharyngeal region in three sprays thrice daily for 5 consecutive days. The primary outcome measures are time to complete resolution of sore throat and relief rate of sore throat. Secondary outcome measures include resolution rate of sore throat, time to relief of sore throat, intensity of sore throat, and change of traditional Chinese medicine syndrome score and clinical signs score from baseline to post-treatment, as well as the occurrence of any adverse events. DISCUSSION: This will be the first clinical trial to investigate the efficacy and safety of QWQYA in the treatment of acute pharyngitis in an adult population in a multicenter, randomized, double-blinded, parallel-group, placebo-controlled manner. Not only might it establish the basis for the efficacy and safety of QWQYA in treating acute pharyngitis, but it might also provide evidence to support the use of Chinese herbal medicine in treating acute pharyngitis and thus support an alternative treatment option for management of acute pharyngitis.
