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
Background: Vaping in adolescents and young adults is increasingly common and has been shown to cause deleterious effects. Little is known about the effects of vaping on risk of coronavirus disease 2019 (COVID-19) among women of reproductive age. This study evaluated whether vaping nicotine and/or cannabis during the year before pregnancy was associated with medically-attended COVID-19 episodes. Methods: This large multicenter cross-sectional retrospective study evaluated women universally screened for vaping during the year before pregnancy as part of standard prenatal care from 9/1/2021 to 3/31/2023. Data came from the electronic health record and included nicotine and/or cannabis vaping during the year before pregnancy (exposure), medically-attended COVID-19 episode during the year before pregnancy (outcome), current and 5-year-history of tobacco smoking status, age, race/ethnicity, neighborhood deprivation index, body mass index, parity and Elixhauser Comorbidity Score. Associations between vaping and medically-attended COVID-19 episodes were estimated using Targeted Maximum Likelihood Estimation (TMLE) adjusting for covariates. Sensitivity analyses were performed after excluding women who had a history of current/former tobacco smoking. Results: The sample of 71,508 reproductive-aged women had a mean (standard deviation) age of 31.7 (5.2) years and 67.6% were non-White. Overall, 2,347 (3.3%) reported vaping nicotine and 3,505 (4.9%) reported vaping cannabis during the year before pregnancy (2.47% vaped nicotine only, 4.10% vaped cannabis only, and 0.81% vaped both). The prevalence of having a medically-attended COVID-19 episode was higher among those who vaped Conclusions: Vaping nicotine only or in combination with cannabis was positively associated with medically-attended COVID-19 episodes among women during the year prior to pregnancy. Future research is needed to understand the mechanisms underlying this association.
