Socio-economic inequalities in blood mercury (Hg) and serum polychlorinated biphenyl (PCB) concentrations among pregnant Inuit women from Nunavik, Canada.
Article in Canadian journal of public health = Revue canadienne de sante publique, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled it.
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
objectiveWe examined the relationships between socio-economic characteristics and mercury (Hg) and polychlorinated biphenyl (PCB) concentrations among pregnant Inuit women from Nunavik.
methodWe used biomonitoring data from 208 pregnant Inuit women recruited in the 14 villages of Nunavik between September 2011 and December 2013. Blood samples were collected to monitor levels of blood Hg and serum congener PCB-153 (surrogate of total PCB concentration). Ratio of omega 3/omega 6 polyunsaturated fatty acids, a validated biomarker of marine country food consumption, was also measured in red blood cell membranes to determine maternal dietary profile. Data on socio-economic characteristics (income and education), health-related lifestyles, and reproductive history were collected through questionnaires. Association between socio-economic characteristics and contaminant concentrations was assessed using linear regressions.
resultsWe observed a significant inverse relationship between education and Hg levels. Lower concentrations of Hg were observed among women who had completed high school compared to women who had not completed high school. However, no association was observed between level of education and concentration of PCBs.
conclusionSocio-economic disparities in maternal exposure to Hg exist in Nunavik. Further research is needed to determine whether environmental health inequalities also exist in other subgroups of the Nunavik population and in other Indigenous communities in Canada.
