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

objectiveAssessment of the frequency of complications observed with various forceps and operative vaginal delivery (OVD) techniques performed at the ABC Medical Center (Mexico City) to evaluate their safety, bearing in mind the importance of decreasing our country's high cesarean section incidence.

methodsWe reviewed 5,375 deliveries performed between the years 2007 and 2012, only 146 were delivered by OVD.

resultsOnly 1.0% of the cases had a serious, life-threatening situation (uterine rupture). The Simpson forceps was the most favored instrument (46%) due to its simplicity of use, effectiveness, and familiarity. Prophylactic use was the most common indication (30.8%) and significant complications observed were vaginal lacerations (p = 0.016), relative risk (RR) of 3.4 (95% confidence interval [CI]: 1.15-10.04), and fourth degree perineal tear (p = 0.016), RR of 3.4 (95% CI: 1.15-10.04).

conclusionsForceps use and other OVD techniques are a safe alternative to be considered, diminishing C-section incidence and its complications.
