Preoperative oral zinc tablet decreases incidence of postoperative sore throat.
Article in Indian journal of anaesthesia, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
BACKGROUND AND
aimsPostoperative sore throat (POST) is very frequently reported after endotracheal intubation. Zinc lozenge has been shown to reduce POST. The aim of this study was to evaluate the effect of dispersible zinc tablet on POST.
methodsEighty-eight patients undergoing surgery with endotracheal intubation were randomly allocated into two groups, to either receive dispersible zinc tablet 40 mg (zinc group) or placebo tablet (control group), 30 min preoperatively. Assessment for incidence and severity was performed for POST, on a 4-point scale (0-3) at 0, 30 min, 2, 4, and 24 h postoperatively. The primary outcome was incidence of POST at 4 h postoperatively. Secondary outcome was severity of POST at the 5 evaluation time points postoperatively. Mann-Whitney U test, Fisher's exact, and Chi-square test were used as applicable.
resultsAt 4 h, there was a significantly lower incidence of POST in zinc group (6.8%) than the control group (31.8%) with a
conclusionPreoperative administration of 40 mg dispersible zinc tablet effectively reduces the incidence and severity of POST in the immediate postoperative period.
