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

backgroundThe aim of this study was to investigate the effect of continuous regulation of laryngeal mask cuff pressure on postoperative sore throat (POST) after laparoscopic cholecystectomy.

methodsPatients underwent laparoscopic cholecystectomy were randomly divided into group E or group C in a 1:1 ratio. Laryngeal mask was inserted after successful induction of general anaesthesia. The product of laryngeal mask used in this study was Hope laryngeal mask airway (H-LMA). Group E: the continuous cuff pressure regulator was used to continuously control the cuff pressure of the laryngeal mask at 40 cmH

resultsA total of 100 adult patients completed the study. The incidence of POST 30 min and within 24 h of extubation was lower in group E than in group C (12% vs. 36%; P = 0.009) (10% vs. 32%; P = 0.013). The severity of POST 30 min and within 24 h after extubation was also lower in group E than in group C (all P<0.05). The incidence of dysphagia 30 min and within 24 h after extubation was lower in group E than in group C (all P<0.05).

conclusionsIn conclusion, the incidence of POST can be reduced by continuously controlling the laryngeal mask cuff pressure at 40 cmH
