The NorthMom study: population-based follow-up of women in a birth cohort to assess pregnancy exposures and effects on breast cancer risk factors.
Observational study in BMC public health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 NorthMom Study (NorthMom) is an observational, population-based cohort designed to determine how the environment during pregnancy affects later health risks among women. The specific focus of NorthMom is breast cancer risk, evaluated through intermediate markers such as breast density, and additional outcomes may be studied in the future.
methodsNorthMom is nested in the larger NorthPop Birth Cohort Study (NorthPop), which was initiated in Västerbotten County, Sweden in 2016 and closed recruitment in 2025. All women previously enrolled in NorthPop are invited to join NorthMom after turning 40 years of age. Women who have moved from the county, have withdrawn or declined follow-up from NorthPop, or are pregnant at the time of invitation are considered ineligible. Those who agree to participate visit the Clinical Research Center at the University Hospital of Umeå in Västerbotten, Sweden. A study nurse collects a blood sample and additional health data, including body composition by Dual-Energy X-ray absorptiometry (DXA). To assess breast density, mammographic images from the Swedish national breast cancer screening program are acquired and evaluated both manually (by a consultant radiologist) and automatically using the Laboratory for Individualized Breast Radiodensity Assessment (LIBRA) software. Measures include classification according to BI-RADS 4 (1-4) and BI-RADS 5 (A-D), as well as continuous densities (%) and dense area (cm DISCUSSION: Analysis of data collected as part of NorthMom and NorthPop will be used to assess relationships between environmental exposures during pregnancy and women's later health, with a focus on breast cancer risk factors such as breast density after age 40.
