Clinical efficacy of a Chinese herbal gel plaster combined with manipulation for lumbar disc herniation: a prospective, randomized, double-blind, placebo-controlled trial.
Trial report in Frontiers in pharmacology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Haitongpi Formula, derived from the Traditional Chinese Medicine (TCM) classic Yizong Jinjian, has shown efficacy for low back pain, fractures, and osteoarthritis. Haitongpi Formula Gel Paste (HTPGP) is a modern dosage form of this formula, but clinical evidence on its effectiveness and safety remains limited. This study was designed to evaluate the clinical efficacy and safety of HTPGP combined with manipulation in relieving chronic pain caused by lumbar disc herniation (LDH). Methods: Adults aged 40-60 years with LDH were randomly assigned to receive Qing dynasty three-movement manipulation plus HTPGP or placebo plaster (PLAGP) for 2 weeks, with 4 weeks of follow-up. The primary outcome was pain intensity measured by the visual analog scale (VAS); secondary outcomes included the Oswestry Disability Index (ODI) and surface electromyography (sEMG). Analyses were performed using generalized estimating equations, repeated-measures ANOVA, and Mann-Whitney U tests. Results: Between October 2024 and June 2025, 100 eligible participants were randomized (HTPGP vs. PLAGP, 1:1). The HTPGP group demonstrated significantly greater VAS improvement from day 7 onwards (Z = 2.644-4.332). ODI scores were consistently lower in the HTPGP group (main effect F = 33.43; time effect F = 227.21; interaction F = 17.19). No significant between-group differences were observed in sEMG outcomes, and no serious adverse events occurred. Conclusion: In patients with LDH, HTPGP combined with manipulation provided greater pain reduction and better functional improvement than those observed in the placebo group, with a favorable safety profile. Larger randomized trials are required to confirm these findings. Trial registration: The trial was registered with the International Traditional Medicine Clinical Trial Registry (http://itmctr.ccebtcm.org.cn/; No. ITMCTR2024000077).
