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
Introduction Postoperative sore throat (POST) is a common complication of endotracheal intubation. This study aims to compare the effect of ultrasonic nebulisation with dexmedetomidine versus clonidine on POST in patients undergoing elective laparoscopic cholecystectomy under general anaesthesia. Methods This prospective, observational, comparative cohort study was initiated after obtaining institutional ethics committee approval and registration with the Clinical Trials Registry of India (CTRI). In one group, 40 patients were ultrasonically nebulised with dexmedetomidine 50 mcg in 4 mL of saline, whereas in another group, 38 patients were ultrasonically nebulised with clonidine 100 mcg in 4 mL of saline. The primary outcome was to compare the efficacy of nebulised dexmedetomidine and clonidine in relieving POST, whereas the secondary outcome was to compare the effect of nebulised dexmedetomidine and clonidine on the haemodynamic parameters at defined time points. Results The demographic data of the study were comparable. The incidence of sore throat was less in the patients nebulised with dexmedetomidine compared to clonidine, which was more evident at six hours (p < 0.001), 12 hours (p < 0.001) and 24 hours after surgery (p = 0.027). The overall change in heart rate over time was comparable in the two groups. The overall change in mean arterial pressure over time was comparable in the two groups except at the time of intubation, when it was statistically significant (p = 0.032). Conclusion The study's findings suggest that nebulisation with dexmedetomidine resulted in a lower incidence and less severe sore throat in postoperative patients compared to nebulisation with clonidine in patients undergoing elective laparoscopic cholecystectomy under general anaesthesia.
