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

objectiveWe investigated the associations of grandmaternal early pregnancy BMI with grand-offspring risks of birth asphyxia-related complications.

methodsIn a nationwide three-generation Swedish cohort, we estimated adjusted relative risks (RRs) of Apgar score 0-3 at 5 min and neonatal seizures for categories of grandmaternal BMI among 315,461 maternal and 203,522 paternal singleton live-born grand-offspring. To address unmeasured confounding by shared familial factors, we used the parental full sisters' BMI as a negative control exposure. In the maternal line, we assessed whether associations with grandmaternal obesity were mediated through maternal obesity.

resultsCompared with normal maternal grandmaternal BMI, RRs (95% CI) of low Apgar score were, respectively, 1.29 (1.06, 1.57) and 1.53 (1.03, 2.28) for overweight (BMI 25.0 to 29.9) and obesity (BMI ≥ 30.0). For neonatal seizures, the corresponding RRs (95% CI) were 1.32 (1.05, 1.66) and 1.81 (1.17, 2.79). Maternal sisters' BMI was unrelated to both outcomes. Maternal obesity mediated < 25% of the associations with maternal grandmaternal obesity. Paternal grandmaternal obesity was related to an increased risk of neonatal seizures; paternal sisters' BMI was unrelated to this outcome.

conclusionsGrandmaternal overweight and obesity are related to increased risks of severe birth asphyxia-related complications in grand-offspring, independent of unmeasured shared familial factors.
