Persistent levator co-activation is not associated with symptoms or bother of obstructed defecation.
Article in International urogynecology journal, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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 and hypothesisThe objective was to determine whether levator contraction during Valsalva (i.e. levator co-activation), as visualised on four-dimensional translabial ultrasound (4D-TLUS), is associated with obstructed defecation (OD).
methodsThis was a retrospective study including patients attending a tertiary urogynecological unit. All underwent an interview, clinical examination and 4D-TLUS. Frequent straining at stool, digitation or sensation of incomplete emptying during defecation were considered symptoms of OD. Archived 4D-TLUS volumes were evaluated, blinded to all other data. Hiatal anteroposterior (AP) diameter (cm) and hiatal area (cm
resultsOverall, 1,383 women attended the unit from May 2013 to July 2016. Seven hundred and eight were excluded because of rectocele (n = 645), enterocele (n = 116) or rectal intussusception (n = 41) and 10 owing to missing data, leaving 665. Mean age was 53 years (16-89), mean body mass index (BMI) 27.3 kg/m
conclusionsLevator co-activation seen on TLUS is not associated with obstructed defecation.
