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

backgroundThe long-term associations between metal mixtures in pregnancy and women's mid-life blood pressure (BP) and hypertension remain unclear.

methodsIn Project Viva (enrolled 1999-2002), we measured nonessential (arsenic, barium, cadmium, cesium, mercury, lead) and essential metals (copper, magnesium, manganese, selenium, zinc) in red blood cells, along with folate and vitamin B12 in plasma, collected during pregnancy. We measured mid-life BP from 2017 to 2021 (median age, 51.2 years). We examined associations of individual metals with BP using linear regression and with hypertension (≥130/80 mm Hg or use of antihypertensive medication) using modified Poisson regression. We used Bayesian kernel machine regression to examine the mixture effects of metals and micronutrients.

resultsThe median follow-up time of the 493 women was 18.1 years (interquartile range, 17.8-18.6 years). After adjustment, a doubling of copper and manganese was associated with 0.75 (95% CI, 0.57-0.99) and 0.80 (95% CI, 0.71-0.91) times the risk of hypertension, respectively. Although higher cesium and selenium levels were associated with a slightly increased risk of hypertension, the 95% CIs were wide and crossed the null. A doubling of vitamin B12 was associated with a 3.64 (95% CI, 1.23-6.04) mm Hg lower systolic BP and a 2.52 (95% CI, 0.72-4.32) mm Hg lower diastolic BP. Bayesian kernel machine regression showed linear associations with no metal-metal or metal-micronutrient interactions. The essential metal mixture was monotonically associated with lower BP, while its association with hypertension showed threshold effects.

conclusionsOptimizing essential metal levels during pregnancy, particularly copper and manganese, along with vitamin B12, may protect against higher BP and hypertension in mid-life women.
