Is there any association between abdominal strength training before and during pregnancy and delivery outcome? The Norwegian Mother and Child Cohort Study.
Article in Brazilian journal of physical therapy. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04431102 (The Effects of the Pilates Method on Pelvic Floor Injuries During Pregnancy and Childbirth), which is not on this map. Cited by 2 papers.
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.

Abstract
backgroundAbdominal strength training before and during pregnancy has been recommended to enhance normal vaginal birth by enabling increased force needed for active pushing. However, to date there is little research addressing this hypothesis.
objectiveTo investigate whether nulliparous pregnant women reporting regular abdominal strength training prior to and at two time points during pregnancy have reduced risk of cesarean section, instrumental assisted vaginal delivery and third- and fourth-degree perineal tears.
methodsAnalysis of 36124 nulliparous pregnant women participating in the Norwegian Mother and Child Cohort Study during the period 1999-2009 who responded to questions regards the main exposure; regular abdominal strength training. Data on delivery outcomes were retrieved from the Medical Birth Registry of Norway. Logistic regression analyses were used to evaluate the association between exposure and outcome before pregnancy and at gestational weeks 17 and 30.
resultsAmongst participants, 66.9% reported doing abdominal strength training exercises before pregnancy, declining to 31.2% at gestational week 30. The adjusted odds ratios were 0.97 (95% CI 0.79-1.19) for acute cesarean section, among those training with the same frequency before and during pregnancy compared to those that never trained. The results were similar for instrumental assisted vaginal delivery and third- and fourth-degree perineal tear.
conclusionThere was no association between the report of regular abdominal strength training before and during pregnancy and delivery outcomes in this prospective population-based cohort.
