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
backgroundPostoperative sore throat, cough, and hoarseness of voice are common sequelae of endotracheal intubation. These symptoms, although self-limiting, are distressing to patients and may affect their perioperative experience and satisfaction. Various methods have been explored to reduce these complications, including the lubrication of the endotracheal tube (ETT) with local anesthetics or simple lubricating agents. However, evidence regarding the comparative efficacy of lignocaine jelly and water-based lubricants remains inconclusive.
aimTo compare the efficacy of lignocaine jelly and water-based lubricating jelly applied over ETTs in reducing postoperative sore throat, cough, and hoarseness of voice in patients undergoing elective surgery under general anesthesia.
methodsThis prospective, comparative study was conducted on 120 adult patients (American Society of Anesthesiologists (ASA) I-II, aged 18-60 years) posted for elective surgeries under general anesthesia with endotracheal intubation. Patients were randomly allocated into two groups: Group L (n=60), where 2% lignocaine jelly was applied to the ETT, and Group W (n=60), where water-based lubricating jelly was applied. Standardized anesthesia techniques were used in both groups. Postoperative assessment of sore throat, cough, and hoarseness of voice was carried out at 1, 6, 12, and 24 hours using a direct questionnaire and graded scoring system. Data were analyzed using SPSS (version 27) (IBM Corp., Armonk, NY), with chi-square and t-tests applied; p<0.05 was considered statistically significant.
resultsBoth groups were comparable in demographic characteristics and intraoperative variables. The overall incidence and severity of postoperative sore throat, cough, and hoarseness were lower in the water-based jelly group compared to the lignocaine jelly group, with statistically significant differences noted particularly at early postoperative intervals. By 24 hours, most symptoms had subsided in both groups.
conclusionWater-based lubricating jelly applied over the ETT is more effective than lignocaine jelly in reducing the incidence and severity of postoperative sore throat, cough, and hoarseness of voice. Being inexpensive, widely available, and devoid of potential systemic side effects of lignocaine, it may be recommended as a safer alternative for routine clinical practice.
