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

introduction and hypothesisThis time-series analysis was carried out to determine if the use of the EPISCISSORS-60®, episiotomy scissors specifically designed to achieve a cutting angle of 60°, would continue to sustain obstetric anal sphincter injuries (OASIS) reductions at our hospital 2 years after its introduction.

methodsWe compared data from 2,342 women delivered in 2014 (prior to the introduction of EPISCISSORS-60®) with that of 4,498 women delivered from 2016 to 2017 (after the introduction of EPISCISSORS-60®).

resultsThere was a reduction of OASIS in all nulliparous vaginal deliveries (NVD; 7.2% vs 5.1% p = 0.05), and a 50% reduction of OASIS (7.5% vs 3.7%) in operative vaginal deliveries (OVD) (p = 0.02). There was a statistically significant association between episiotomies performed with EPISCISSORS-60® and a reduction in OASIS (SVD: 6.9% vs 1.5% p = 0.006; OVD:28.6% vs 2.6% p < 0.0001). Additionally, there was an increase in the use of episiotomies in all nulliparous vaginal deliveries (29% vs 33.7%; p = 0.01). We also found a 78% reduction of OASIS with episiotomies compared with no episiotomies in the 2016-2017 group (6.9% vs 1.5% p = 0.006).

conclusionsOur results suggest that there might have been a sustained reduction in OASIS rates associated with using EPISCISSORS-60®.
