Marijuana Use during Pregnancy and Preterm Birth: A Prospective Cohort Study.
Article in American journal of perinatology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers, 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe aim of this study is to estimate the association between marijuana use during pregnancy and total, spontaneous and indicated preterm birth. STUDY
designProspective cohort study of women receiving antenatal care at The Ohio State University from 2010 to 2015. Marijuana use was assessed by questionnaire, record abstraction, and urine toxicology. Women were followed through the end of pregnancy. Relative risks were assessed with Poisson regression and time to delivery with proportional hazard models.
resultsOf 363 eligible women, 119 (33%) used marijuana in pregnancy by at least one measure. In this high-risk cohort, preterm birth occurred to 36.0% of users and 34.6% of nonusers (
conclusionMarijuana use was not associated with total preterm birth in this cohort, suggesting that among women already at high risk of preterm birth, marijuana does not increase risk further. However, there was a suggestion that pregnant women who use marijuana may deliver earlier, particularly from spontaneous preterm birth, than women who do not use marijuana. KEY POINTS: · Marijuana was not associated with risk of all preterm birth.. · Marijuana was not associated with reduced time to delivery.. · However, users had reduced time to spontaneous preterm birth..
