Trial reportBMJ (Clinical research ed.)2004
Randomised controlled trial of pelvic floor muscle training during pregnancy.
Trial report in BMJ (Clinical research ed.), 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02582580 (Effects of Perineal Massage, Vaginal Dilator and Pelvic Floor Muscles Training on the Perineal Integrity Primiparous), which is not on this map. Cited by 27 papers, 7 of them syntheses 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.

Abstract
objectivesTo examine a possible effect on labour of training the muscles of the pelvic floor during pregnancy.
designRandomised controlled trial.
settingTrondheim University Hospital and three outpatient physiotherapy clinics in a primary care setting.
participants301 healthy nulliparous women randomly allocated to a training group (148) or a control group (153).
interventionA structured training programme with exercises for the pelvic floor muscles between the 20th and 36th week of pregnancy.
main outcome measuresDuration of the second stage of labour and number of deliveries lasting longer than 60 minutes of active pushing among women with spontaneous start of labour after 37 weeks of pregnancy with a singleton fetus in cephalic position.
resultsWomen randomised to pelvic floor muscle training had a lower rate of prolonged second stage labour (24%, 95% confidence interval 16% to 33%; 22 out of 105 women were at risk (undelivered) at 60 minutes in the survival analysis) than women allocated to no training (38% (37/109), 28% to 47%). The duration of the second stage was not significantly shorter (40 minutes v 45 minutes, P = 0. 06).
conclusionsA structured training programme for the pelvic floor muscles is associated with fewer cases of active pushing in the second stage of labour lasting longer than 60 minutes.
