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

Purpose: Vaginal delivery is the most common mode of childbirth, and women often experience severe uterine contraction pain (UCP) for several days postpartum, which can significantly impair postpartum recovery. Acupuncture has proven efficacy in the management of multiple pain conditions. This trial aimed to evaluate the analgesic efficacy and safety of acupuncture for managing postpartum UCP following vaginal delivery. Patients and Methods: This trial was designed as a prospective, randomized controlled trial with blinding of participants, outcome assessors, and data analysts. A total of 236 participants were planned for recruitment and were randomly assigned in a 1:1 ratio to either the Verum Acupuncture (VA) group or the Sham Acupuncture (SA) group. The VA group underwent verum acupuncture at four bilateral acupoints (ST36, LR3, SP8, and GB41), for a total of eight needling sites. The SA group received simulated needling with a non-penetrating blunt needle via the Park Sham Device (PSD). Acupuncture was administered twice daily for three consecutive days, starting on the day of vaginal delivery, with needles retained for 30 minutes per session. The primary outcome was defined as the UCP level assessed by the Visual Analog Scale (VAS) on postpartum day 3. Secondary outcomes included UCP levels at postpartum days 1, 2, 10, and 17, as well as the intensity, frequency, and duration of UCP, vaginal blood loss, lactation volume, and psychological scores measured by the Edinburgh Postnatal Depression Scale (EPDS), Self-Rating Anxiety Scale (SAS), and Short Form-36 Health Survey (SF-36). Conclusion: The research results are expected to provide credible evidence for the efficacy of acupuncture as a complementary treatment for UCP following vaginal delivery.
