Risk factors associated with anal sphincter tear difference among midwife, private obstetrician, and resident deliveries.
Article in International urogynecology journal and pelvic floor dysfunction, 2008. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
To identify risk factors that account for the difference in anal sphincter tear (AST) among midwife, private obstetrician, and resident deliveries. We performed a retrospective review of our obstetrical database and used logistic regression analysis to identify risk factors for AST. The relationship between delivery technique and AST was evaluated by comparing AST increase between vaginal deliveries without and with an episiotomy among the three categories of providers. After adjusting for risk factors, private obstetricians (OR: 1.81, 95% CI: 1.27-2.56) and residents (OR: 1.60, 95% CI: 1.20-2.15) had a higher rate of AST during vaginal delivery than midwives. Episiotomy increased the odds of AST by four-fold for midwives, two-fold for private obstetricians, and eight-fold for residents. Although midwife and resident's delivery methods were associated with more AST, neither experienced this complication more frequently than private obstetricians. This suggests that midwives and residents probably misdiagnosed some AST.
