Typologies of Maternal Substance Use in Pregnancy: Latent Classes and Sociodemographic Correlates in a U.S. Sample.

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
objectiveSubstance use patterns vary considerably in the general population, yet little is known about patterns before and during pregnancy. The purpose of this study was to describe single substance and polysubstance use (PSU) before and during pregnancy among recent births in the United States and compare exposure patterns.
methodWe used data from the Pregnancy and Risk Assessment Monitoring System (PRAMS) postpartum survey for 2016-2018 to estimate the prevalence and identify patterns of substance use by participants 1 to 3 months before and during pregnancy. Data on use of cigarettes, cannabis, opioids, amphetamines, heroin, and cocaine were available for seven states. We used latent class analysis to identify patterns of substance use and tested whether participants with those patterns differed by age, income, race/ethnicity, and pre-pregnancy alcohol use. Analyses were weighted using PRAMS' state-level weights.
resultsWe studied 15,429 participants representing 384,918 live, singleton births. Approximately half (51.3%) were 20-29 years old, 42.3% were above 200% of the Federal Poverty Level, and 73.3% were non-Hispanic White. We identified seven latent classes of maternal substance use: minimal users (70.7%), pre-pregnancy cigarette users (10.5%), persistent cigarette users (6.8%), pre-pregnancy cannabis users (5.5%), broad PSU (3.6%), opioid-only users (1.9%), and persistent cigarette/opioid co-users (1.0%). Participants in these groups differed significantly by age, income, race/ethnicity, and pre-pregnancy alcohol use (
conclusionsThis novel empirical classification of single substance and PSU could help to further our understanding of the impact of PSU on perinatal health and to design interventions for maternal substance use.
