Device measured physical activity before pregnancy and the risk of adverse pregnancy outcomes in the HUNT study: a population-based cohort study.

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
backgroundAdverse pregnancy outcomes (APOs), including gestational diabetes mellitus (GDM), hypertensive disorders of pregnancy (HDP), small for gestational age (SGA) offspring, preterm birth and placental abruption, pose significant short and long-term health consequences for mothers and their offspring. Engaging in physical activity may reduce the risk of APOs. We aimed to examine the association between objectively measured physical activity before pregnancy and risk of APOs.
methodsThe study population consisted of women with one or more singleton births registered in the Medical Birth Registry of Norway (MBRN) after participating in the fourth survey of the Trøndelag Health Study (HUNT4, 2017-2019). HUNT4 provided data on accelerometer measures on physical activity. We used multivariable adjusted logistic regression models to estimate associations between physical activity (total daily physical activity and metabolic equivalent of task (MET) min/week of moderate to vigorous physical activity (MVPA)) and risk of APOs (GDM, HDP, SGA offspring, preterm birth and/or placental abruption).
resultsAmong 700 women included in the study population, 145 (20.7%) experienced at least one APO. Compared to women in the lowest tertile of total physical activity/day, those in the highest tertile had lower odds of GDM (OR 0.19; 95% CI: 0.38-0.93) and potentially lower odds of any APO (OR 0.69; 95% CI: 0.43-1.11). Women with higher levels of total daily physical activity and higher levels of MVPA had lower odds for the composite outcome HDP, GDM, and/or SGA (OR 0.49; 95% CI: 0.28-0.87, highest tertile compared to lowest tertile and OR 0.53; 95% CI: 0.28-1.01, > 1000 MET minutes/week compared to < 500 MET minutes/week).
conclusionsIncreased prepregnancy physical activity, including total daily activity, may reduce the risk APOs. Promoting preconceptional everyday activity could be key to improving pregnancy health. Larger studies are needed to confirm these findings.
