Effects of prenatal yoga on birth outcomes in nulliparous women: a systematic review and meta-analysis of randomized controlled trials.
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
backgroundPrenatal yoga uniquely integrates moderate aerobic activity with mindfulness‑based stress reduction, diaphragmatic breathing, and targeted pelvic‑floor conditioning. This study aimed to investigate whether yoga could influence the rates of cesarean section, episiotomy, perineal laceration, vaginal midwifery, preterm birth, and total labor time during delivery compared to standard nursing care.
methodSearches were conducted in MEDLINE, OVID, Scopus, PubMed, China Biology Medicine (CBM), Wiley, BMJ, JAMA, The Cochrane Library, Web of Science, VIP database, Wanfang database, CNKI, ClinicalTrials.gov, and the Cochrane Central Register of Controlled Trials, using a combination of keywords related to "prenatal yoga," "pregnancy yoga," "yoga birth RCT," "pregnant woman yoga," and pregnancy outcomes from database inception until December 2023. Bias assessment followed the Cochrane Handbook guidelines. The random-effects model calculated relative risk or mean differences with confidence intervals. Randomized controlled trials comparing yoga practice with general nursing exclusively during labor were included. Primary outcomes were rates of cesarean section, episiotomy, perineal laceration, vaginal midwifery, and preterm birth. Secondary outcomes included total labor time during delivery. Statistical analysis was performed using RevMan 5.4.
resultsThe meta-analysis included 14 randomized controlled trials with 3637 women. The control group received general nursing, while the experimental group underwent yoga classes and practice in addition to general nursing. The risk of bias was generally low. The rates of cesarean section (RR = 0.45, 95%CI: 0.38, 0.54, P < 0.01), vaginal delivery (RR = 0.66, 95%CI: 0.47, 0.93, P = 0.02), premature birth (RR = 0.29, 95%CI: 0.15, 0.56, P < 0.01), and perineal laceration (RR = 0.41, 95%CI: 0.25, 0.69, P < 0.0007) in the experimental group were lower than in the control group. Additionally, the total labor time for the experimental group was shorter than for the control group [MD=-2.10, 95%CI: -2.42, -1.79, P < 0.0001].
conclusionsCombining yoga practice with general nursing contributes to lower cesarean rates, shortened delivery times, reduced perineal lacerations, episiotomies, and preterm births.
