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

objectivesThe aims of the study were to systematically review the literature and to synthesize the evidence for the effectiveness of botulinum toxin injection to the pelvic floor muscles for treating pelvic floor myofascial pain in female patients.

methodsThis systematic literature search was performed in February 2018 and updated in September 2019. Articles were screened based on predefined criteria: (1) adult population, (2) female patients, (3) treatment of pelvic pain by transvaginal botulinum toxin injection into the pelvic floor, (4) published in English or English translation available, (5) study design including randomized controlled trials, cohort studies, and case series with more than 10 participants, and (6) quantitative report of pain scores. Nine studies were included in the primary analysis, and an unpublished study was included in a sensitivity analysis. A random effects model with robust variance estimation was used to estimate the pooled mean difference in patient-reported pain scores after botulinum toxin injection.

resultsA statistically significant reduction in patient-reported pain scores was noted at 6 weeks after botulinum toxin injection (mean difference, 20.3; 95% confidence interval, 11.7-28.9) and continued past 12 weeks (mean difference, 19.4; 95% confidence interval, 14.6-24.2). Significant improvement was noted in secondary outcomes including dyspareunia, dyschezia, and quality of life.

conclusionsThis systematic review and meta-analysis support the conduct of future, large-scale randomized controlled trials to determine the efficacy and optimize administration of botulinum toxin injections for treatment of pelvic floor myofascial pain and associated symptoms in women.
