Non-pharmaceutical Chinese Medical Therapies for Nausea and Vomiting of Pregnancy: An Umbrella Review of Systematic Reviews and Meta-analyses of Randomized Controlled Trials.

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
backgroundNausea and vomiting of pregnancy (NVP) are common symptoms during early pregnancy that significantly impact maternal quality of life and fetal development. Given concerns about the safety of pharmacological treatments, non-pharmaceutical Chinese medical therapies (NPCT) have been new topics of great interest due to their minimal side effects.
objectiveTo evaluate the efficacy and safety of NPCT for the management of NVP through an umbrella review of systematic reviews and meta-analyses of randomized controlled trials.
methodsEligible data were retrieved from online databases up to August 31, 2024 for subsequent analyses. The quality of included reviews and the certainty of evidence were evaluated using the AMSTAR-2 tool and the GRADE criteria, respectively. Subgroup analyses were performed based on intervention types, treatment methods, and control conditions to explore potential sources of heterogeneity. Primary outcomes included the severity of NVP, treatment effectiveness, and safety.
resultsThis study included a total of 22 systematic reviews or meta-analyses on various NPCT interventions. The AMSTAR-2 assessment rated 6 studies as high quality, 2 as moderate, and 14 as low or very low quality. The GRADE evaluation categorized evidence as moderate for 5 comparisons, low for 15, and very low for 5 out of the 25 outcome measures. Further analyses revealed the superior effects of acupuncture in decreasing the Pregnancy-Unique Quantification of Emesis score (MD, -1.32; 95% CI, -1.69 to -0.95; moderate evidence), increasing the rate of negative urinary ketone bodies (RR, 1.32; 95% CI, 1.14 to 1.53; moderate evidence); as well as reducing anxiety (MD, 0.78; 95% CI, -1.13 to 2.6; moderate evidence) and depression scores (MD, 0.20; 95% CI, -2.05 to 2.46; moderate evidence).
conclusionsNPCT, particularly acupuncture, may have potential benefits in alleviating NVP. However, due to limited overall quality and certainty of evidence, studies with more rigorous designs and larger sample sizes should be included to produce higher-quality evidence, thereby better informing clinical practice.
