Differences in pregnancy complications and outcomes by fetal gender among Japanese women: a multicenter cross-sectional study.
Article in Scientific reports, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 13 papers.
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
The association between fetal gender and rare pregnancy complications has not been extensively investigated, and no studies have examined this association in Japanese women. Thus, we used a large Japanese birth registry database to investigate the extent to which fetal gender affects various pregnancy outcomes. We analyzed 1,098,268 women with a singleton delivery with no congenital anomaly at 22 weeks or later between 2007 and 2015. Women carrying a male fetus had a significantly higher risk of placental abruption (adjusted risk ratio [aRR] 1.15, 95% confidence interval (CI) 1.10-1.20)], preterm delivery (aRR 1.20, 95% CI 1.19-1.22), instrumental delivery (aRR 1.27, 95% CI 1.26-1.29), and cesarean delivery (aRR 1.01, 95% CI 1.00-1.02). In contrast, they had a significantly lower risk of preeclampsia (aRR 0.92, 95% CI 0.89-0.94), placenta accreta (aRR 0.90, 95% CI 0.85-0.96), atonic hemorrhage (aRR 0.95, 95% CI 0.93-0.96), and maternal blood transfusion (aRR 0.95, 95% CI 0.92-0.99). Our findings demonstrate a significant association between fetal gender and various pregnancy complications and delivery outcomes among Japanese women.
