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

objectivesOne adverse effect of electroconvulsive therapy (ECT) is dental fracture; thus, a bite guard and muscle relaxants are used to prevent it. Earlier research reported varying rates of dental fracture, but there is no large-scale study on the incidence of dental fracture during ECT. This study aimed to examine the incidence of dental fracture during ECT and to investigate whether the incidence differs between different sexes, age groups, diagnosis groups, electrode placements, or number of treatment sessions.

methodsThis register-based study used data from the Swedish national quality register for ECT. All hospitals offering ECT report to this register, and the coverage ratio is about 90%. All registered patients who started an ECT series between January 2012 and January 2019 were included in this study, with the data representing 16,681 individuals, 38,862 series, and 254,906 sessions.

resultsForty-six dental fractures were identified, giving an incidence of dental fracture of 0.2% per series, 0.02% per session, and 0.3% per individual. We did not find any significant associations between dental fracture rates and male or female populations, age, or different diagnosis groups, nor was there any significant difference between dental fracture rates and electrode placement. The mean number of treatments was significantly higher in the dental fracture group than in patients without dental fracture.

conclusionsThere is a minimal risk of dental fracture during ECT. Our findings, together with those of other studies, provide further motivation for the use of a bite guard and muscle relaxant.
