Exercise during pregnancy and cesarean delivery: North Carolina PRAMS, 2004-2005.
Article in Birth (Berkeley, Calif.), 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe current rate of cesarean delivery in the United States is 31 percent. Previous studies have suggested that exercise during pregnancy may be associated with a lower risk of cesarean delivery, but sample sizes were small and methods often inadequate. This study examined whether or not an association exists between prenatal exercise and delivery mode using data from the 2004 and 2005 North Carolina Pregnancy Risk Assessment Monitoring System (PRAMS) survey.
methodsPRAMS postpartum questionnaire responses about frequency of exercise during the last 3 months of pregnancy for 1,955 women without a prior cesarean delivery were linked to birth certificates.
resultsAmong 1,342 women delivering at term, exercise was not associated with delivery mode in this data set: compared with women exercising less than once a week, neither women exercising one to four times per week nor those exercising five times or more per week had an altered risk of cesarean (risk ratio [RR] [95% confidence limit] [CL] 0.89 [0.69-1.15], 1.04 [0.66-1.64], respectively, adjusted for parity, gestational age, hypertension). Among 613 women delivering preterm, the results were also not statistically significant, but a compelling trend toward a protective effect could be seen (RR [95% CL] 0.65 [0.38-1.13], 0.62 [0.29-1.33]).
conclusionsMaternal self-reported frequency of exercise during pregnancy was not associated with a reduced risk of cesarean delivery. Larger studies with better exposure ascertainment may provide a more definitive answer.
