Associations Between Duration of Lactation and Maternal Risk of Obesity-Related Cancers-A Historical Birth Cohort Study.
Article in Maternal & child nutrition, 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.

Lactation may protect mothers against certain cancers, such as breast- and obesity-related cancers (ORC). However, the evidence is limited and has methodological shortcomings. Therefore, we investigated the associations between lactation durations and the maternal risk of ORC as well as endometrial, ovarian, and postmenopausal breast cancer individually. We included 6880 mothers from the Copenhagen Perinatal Cohort giving birth between 1959 and 1961. Information on duration of predominant and any lactation was collected 1 year postpartum. We used the International Agency for Research on Cancer definition of ORC, including 13 cancers. Cancer diagnoses were obtained from The Danish Cancer Registry (n
