Lessons learned from longitudinal biomonitoring and birth cohort studies: informing the future of reproductive health research in Canada.
Article in Environmental health : a global access science source, 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
Longitudinal biomonitoring studies during preconception, pregnancy and early childhood are highly valuable tools for assessing environmental chemical exposures during sensitive windows and their effects on health and development. For the past 15 years, the Maternal-Infant Research on Environmental Chemicals (MIREC) Research Platform has been Canada's flagship study of the long-term effects of early life exposure to environmental chemicals. In light of the evolving scientific and legislative landscapes and need to address emerging research questions, MIREC Platform researchers at Health Canada consulted with scientific investigators of other cohort studies to inform the development of a future preconception or pregnancy longitudinal biomonitoring study. This effort included 1) hybrid consultation meetings on Dec 6, 2024 (Toronto, ON) and Jan 21, 2025 (Ottawa, ON) and 2) a virtual seminar series from October 2024 to June 2025 hosted by the Health Canada MIREC team. Our objective here is to share lessons learned from this consultation. We report on key lessons learned related to the themes of: 1) participant engagement, recruitment and retention, 2) validity and causal inference, and 3) study longevity. While the ultimate goal of this consultation was to inform future longitudinal biomonitoring studies in Canada, the content is largely generalizable and relevant to others planning, modifying, or evaluating observational research in reproductive and environmental epidemiology.
