Reducing obstetric anal sphincter injuries using perineal support: our preliminary experience.
Article in International urogynecology journal, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers, 1 of them a synthesis that pooled 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.
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 hypothesisObstetric anal sphincter injuries (OASIs) are associated with significant short-term and long-term morbidity. Over the past decade, there has been a steady rise in the rate of OASIs. There is therefore a compelling need to identify strategies to minimize OASIs. The objective of this study was to determine if perineal support at the time of vaginal delivery can reduce the incidence and severity of OASIs.
methodsAll labour ward staff including midwives and doctors were invited to train in the technique of perineal support during vaginal delivery. Two experts from Norway conducted workshops with practical hands-on training on pelvic models. The midwives and doctors underwent further training with women in labour, and mandatory training was continued within the department. All midwives and doctors were instructed to support the perineum during both spontaneous and assisted vaginal delivery.
resultsFrom April 2011 to November 2014, 11,135 women underwent vaginal delivery. The OASI rate decreased from 4.7 % to 4.1 % (p = 0.11). There was a significant reduction (0.9 % to 0.3 %, p < 0.001) in 3c third-degree and fourth-degree tears (major OASIs). In a multivariate analysis, perineal support was associated with a significant reduction in the rates of OASIs (23 %; OR 0.77, 95 % CI 0.63 - 0.95, p = 0.01]) and major OASIs (71 %; OR 0.34, 95 % CI 0.17 - 0.69, p = 0.03).
conclusionsThis interventional study showed that perineal support during vaginal delivery can reduce the risk of major OASIs. With sustained reinforcement of this intervention programme, we anticipate a further reduction in OASI rates.
