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 hypothesisThis study was conducted to evaluate the effects of an alternative model of birth (AMB) on the incidence of assisted vaginal delivery (AVD) and perineal trauma (PT).
methodsOne hundred ninety-nine women with epidural anesthesia were randomized to a traditional model of birth (TMB) (n = 96) or AMB (n = 103). Women in TMB pushed immediately after complete dilatation and delivered in lithotomy position. In AMB, women followed a postural changes protocol while they delayed pushing and used a specific lateral position for delivery.
resultsAMB was associated with a significant reduction in AVD compared with TMB (19.8% vs 42.1%, p<0.001). TMB was strongly associated with AVD (OR = 4.49; p< 0.05), which, in turn, was significantly associated with nulliparity (OR = 5.52; p<0.005) and fetal head unengaged at full dilatation (OR = 5.35; p<0.05). AMB significantly increased the intact perineum rate compared with TMB (40.3% vs 12.2%, p<0.001). Episiotomy rate was significantly reduced in AMB (21.0% vs 51.4%, p<0.001).
conclusionA combination of postural changes during the passive expulsive phase of labor and lateral position during active pushing time is associated with reductions in AVD and PT.
