Dry eye disease due to meibomian gland dysfunction treated with Pinggan Yuyin Qingre formula: a stratified randomized controlled trial.
Trial report in Journal of traditional Chinese medicine = Chung i tsa chih ying wen pan, 2023. 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
objectiveTo observe the clinical efficacy on improving the quality of meibum in patients suffer from dry eye disease (DED) due to meibomian gland dysfunction (MGD) with hyperactivity ofdue todeficiency pattern after being treated with Pinggan Yuyin Qingre formula (, PGYYQR).
methodsTotally 120 patients who met the inclusion criteria were included and stratified into three levels according to the level of MGD (1-3), and patients in each level was randomly allocated into the treatment group and control group according to a 1∶1 ratio. Both groups were treated with sodium hyaluronate eye drops, and the treatment group was also given PGYYQR granules. Both groups were treated continuously for eight weeks. The score of the properties of meibomian gland (MG) secretion, the score of the palpebral margins, the average noninvasive tear breakup time (NITBUTav), lipid layer thickness (LLT), and Traditional Chinese Medicine (TCM) syndrome efficacy were compared between the two groups after treatment.
resultsA total of 116 cases were included in the statistical analysis. The differences were statistically significant in the score of the properties of MG secretion, the score of the palpebral margins, and NITBUTav between the two groups after treatment, the treatment group was superior to the control group; there was no evidence of a difference in LLT. In terms of TCM syndrome efficacy, the total effective rate was 84.7% in the treatment group and 50.9% in the control group, with the statistically significant difference. None of the included cases had adverse reactions.
conclusionsPGYYQR is effective in improving the quality of meibum, and the tear film stability which thereby relieving the ocular symptoms in MGD-related DED patients with hyperactivity ofdue todeficiency pattern.
