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

objectiveThe American College of Gynecology (ACOG) recommendation does not limit air travel during pregnancy, yet the evidence for air travel effect on adverse pregnancy outcomes is limited and debatable. Study objectives were to examine the association between air travel during pregnancy and preterm birth together with decreased birth weight. STUDY

designA retrospective cohort study.

methodsThe study evaluated 628,292 women who gave birth to singleton infants from 9/2000 to 9/2016 and classified them into "air travel during pregnancy" or not, based on flight insurance as proxy. Multiple linear regression models were utilized to examine the relationship between air travel during pregnancy and newborn's gestational age and birth weight, while accounting for socioeconomic status, diabetes, high-risk pregnancies, and smoking.

resultsA total of 41,677 (6.6%) births of women who air traveled during pregnancy was included, and 586,615 (93.4%) births of women who did not. Air travel during pregnancy was associated with a statistically significant (p<0.0001) but negligible increase in birth weight (9 gr. 95% CI: 4.8 to 14.5 gr.) and gestational age (0.36 days. 95% CI: 0.24-0.48).

conclusionThe study results provide no evidence that air travel during pregnancy is related to adverse effects on gestational age or birth weight. These findings corroborate the current recommendations of ACOG.
