Zinc supplementation for postoperative sore throat prevention: evidence from a systematic review and meta-analysis.
Review in Journal of dental anesthesia and pain medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Postoperative sore throat (POST) is a frequent complication of tracheal intubation that compromises patient comfort and satisfaction. This is due to airway irritation and inflammation. Zinc, which is known for its anti-inflammatory and wound-healing effects, has been investigated as a preventive treatment for POST. This protocol was registered in PROSPERO (CRD420250651708).Three databases, PubMed, The Cochrane Central Register of Controlled Trials, and Clinicaltrials.gov were searched using the keywords "Post operative sore throat," and "zinc." A literature search led to the retrieval of six clinical trials, of which three studies were included in the meta-analysis and all six studies were included in the systematic review. The data were synthesized using Cochrane Review Manager v.5.4.1. The Cochrane risk-of-bias 2.0 tool was used to assess the methodological quality of evidence. The pooled analysis included 248 patients (105 males and 143 females). Study findings suggested that zinc reduces the overall incidence of POST in comparison to placebo (P < 0.0001, OR = 0.29 [95% CI 0.16-0.53], I
