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

backgroundPostoperative scarring of the face can cause a serious psychological burden on people. Botulinum toxin type A has shown potential effectiveness in preventing scarring after facial surgery. The study aims to evaluate the role of botulinum toxin type A in postoperative scar management.

methodsWe searched PubMed, Embase, MEDLINE, the Cochrane Library (CENTRAL), and Web of Science for all randomized controlled trials (RCTs) on the use of botulinum toxin type A in the treatment of postoperative facial scars, including all English articles published up to April 15, 2024.

resultsTwelve randomized controlled trials involving 351 patients undergoing facial surgery were included. Quantitative analysis, STATA 17.0 software was used for meta-analysis, and fixed-effect and random-effects models were selected according to the size of heterogeneity, and the results were expressed as SMD and 95% CI for continuous data and OR and 95% CI for dichotomous data. Subgroup analyses were performed according to the different control groups. The OR and 95% CI of adverse effects were 1.74 (0.41-7.43). The p value of adverse reactions and PSAS results was greater than 0.05.

conclusionDue to the small heterogeneity of scar width, OSAS, and PSAS, SMD and 95% CI were -1.00 (-1.20 to 0.80), -0.61 (-1.0 to 0.13), and -0.08 (-0.56 to 0.39), respectively, using a fixed-effect model. Due to large heterogeneity, VAS and VSS scores were scored using a random-effects model, with SMDs and 95% CIs of 1.00 (0.47-1.53) and -0.41 (-0.73 to 0.1), respectively.
