Reproductive Outcomes in Women Born With Low Birth Weight, Preterm or Small for Gestational Age: A Population-Based Register Study.
Article in BJOG : an international journal of obstetrics and gynaecology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveTo evaluate if the reduced likelihood of reproducing among women born small for gestational age (SGA), preterm (PT) or with low birth weight (LBW) persists towards the end of their reproductive era and to evaluate their use of medically assisted reproduction (MAR).
designPopulation-based register study.
settingSweden. POPULATION/SAMPLE: Women born in Sweden between 1973 and 1993 (n = 1 000 148).
methodsData was retrieved from registers, among others the Swedish Medical Birth Register. The study population was stratified into two cohorts, born 1973 to 1983 and 1984 to 1993. The likelihood of giving birth was analysed using a Cox Proportional Hazards model.
main outcome measuresGiving birth to at least one child.
resultsWomen born SGA, PT or LBW had a lower probability of giving birth (presented as HR), adjusted for sociodemographic factors, with 95% CI: SGA: HR 0.94 (0.93-0.96); PT: HR 0.95 (0.94-0.96); and LBW: HR 0.90 (0.88-0.92) but no reduction was seen for women in the younger cohort born SGA (HR 0.98 [0.95-1.01]). Women born SGA or LBW had a lower chance of childbirth after MAR (SGA 80.3%, LBW 80.0%) compared to women born with normal weight (84.6%, p < 0.001) as well as an increased risk of being treated with oocyte donation (SGA 5.5% vs. 2.5%, p < 0.001; LBW 5.0% vs. 2.5%, p < 0.001).
conclusionThe decreased probability of parenthood for women born LBW, SGA, or preterm was even more evident after a longer follow-up time. When pursuing MAR with their own oocytes, they had a lower chance of conceiving.
