1 · What the graph read from 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.

2 · The registry

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

objectiveLactation may help curb diabetes risk and is also known as an excretion route for some environmental pollutants. We evaluated associations of lifetime lactation history with serum concentrations of persistent organic pollutants (POPs) in the National Health and Nutrition Examination Survey 1999-2006, and examined whether potentially diabetogenic POPs account for associations between lactation and diabetes. RESEARCH DESIGN AND

methodsAmong 4479 parous women, breastfeeding history was defined as the number of children breastfed ≥1 month. Diabetes was identified by self-report or hemoglobin A1c >6.5%. Twenty-four POPs were measured in serum among subsamples of 668 to 1073 participants.

resultsCompared with women without lactation history, odds ratios (95% confidence intervals) of having diabetes among those with 1-2 and ≥3 lactation periods were 0.83(0.61, 1.13) and 0.63(0.44, 0.91; P trend=0.03). Lifetime lactation history was inversely associated with serum concentrations of 17 out of the 24 organochlorine pesticides, polychlorinated biphenyl congeners (PCBs), and perfluoroalkyl substances (Ptrend<0.05). Comparing the ≥3 lactations group with women without a lactation history, the relative reduction of POPs ranged from 12% (PCB-196) to 30% (oxychlordane). The inverse association between lactation and diabetes was slightly attenuated after adjustment for POPs. Age-stratified analyses showed that the inverse association between lactation periods and serum POP concentrations was observed primarily among participants <60 years, whereas age did not significantly modify the association between lactation history and diabetes prevalence.

conclusionCrudely-classified lifetime lactation history was inversely associated with concurrent serum POP concentrations and diabetes prevalence. Prospective studies are needed to clarify how lactation could complement diabetes prevention through decreasing the POP body burdens.
