1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study aimed to evaluate the efficacy of a single preoperative 15 mg sublingual dose of melatonin in reducing surgical discomfort, pain, edema, and trismus following mandibular third molar extraction. MATERIALS AND

methodsA randomized, double-blind, placebo-controlled trial was conducted with 46 patients allocated to receive melatonin (n = 22) or placebo (n = 24) 45 min before surgery. The primary outcomes were intraoperative pain and discomfort and postoperative pain. Secondary outcomes included patient-perceived edema (VAS-Edema, days 1-5), trismus (5-point scale, days 1-5; interincisal measurement, day 7), and rescue medication consumption.

resultsNo statistically significant differences were observed between the melatonin and placebo groups for any outcome. Intraoperative discomfort (QCirDental total score, p = 0.54) and pain (VAS, p = 0.67) were comparable. Similarly, postoperative pain levels across all time points (p = 0.67), edema over five days (p = 0.26), and trismus based on self-assessment (all days p > 0.50) and clinical measurement (p = 0.79) did not differ.

conclusionWithin the limitations of this clinical trial, a single 15 mg preoperative dose of sublingual melatonin was not superior to placebo in alleviating surgical discomfort, pain, edema, or trismus after third molar extraction. CLINICAL RELEVANCE: Clinically, these findings suggest that melatonin may have limited effectiveness in managing common complications in oral surgery.
