Differences between breech and cephalic neonates born after planned cesarean section: a systematic review.
Synthesis in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundA growing number of studies have found that breech presentation is related to preexisting diseases and may affect future fetal development. This study aimed to compare the differences between breech presentation and cephalic presentation and explore the underlying mechanisms of adverse outcomes caused by fetal station itself.
methods‘PubMed’, ‘Embase’ and ‘Cochrane Library’ were searched from inception to October 21, 2022. Comparative studies containing ‘prelabor CS’ or ‘elective CS’ of cephalic and breech presentation were included. A total of 585 studies were included, and 5 studies were eligible for final research. Review Manager 5.4.1 was used for data synthesis.
resultsThe mortality of breech group is not different from that of cephalic group (RR 0.69, 95% CI 0.09–5.13, p = 0.71). No differences in infant (< 1 year) and neonatal (0–27 days) mortality were found between the breech and cephalic presentations (RR 1.56, 95% CI 0.86–2.82, p = 0.14). However, breech group was found to have lower birth weight (p < 0.002), umbilical coiling index(p < 0.0001), and bone SOS (p = 0.03 )than cephalic group.
conclusionsThe breech presentation itself may not be related to adverse pregnancy outcomes, and more attention is needed for further exploration.
