Comparing the Effect of Subcutaneous and Intradermal Mesotherapy on Pain and Function in Knee Osteoarthritis: A Randomized Clinical Trial : Short title: Subcutaneous vs. Intradermal Mesotherapy in Knee Osteoarthritis.

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: Knee osteoarthritis (KOA) is the most common form of osteoarthritis and is associated with pain and functional impairment. Mesotherapy, which involves localized intradermal or subcutaneous injection of active agents, may provide targeted pain relief. This study aimed to compare the effects of intradermal and subcutaneous mesotherapy on pain and function in patients with KOA. Materials and Methods: A single-center, randomized, assessor-blinded clinical trial was conducted in Isfahan, Iran, between 2023 and 2024 among patients with mild-to-moderate KOA. Each patient received six sessions of intradermal or subcutaneous piroxicam-lidocaine mesotherapy at six acupuncture points over three weeks (two sessions per week). Pain and function were assessed at baseline, immediately after treatment, and one month after treatment. Statistical analyses included chi-square tests for qualitative variables, independent-samples t-tests for quantitative variables, and repeated-measures analysis of variance to assess changes over time. Statistical significance was set at P<0.05. Results: A total of 50 patients were included. The demographic characteristics and baseline pain and function scores did not differ significantly between the two groups. At the one-month follow-up, the intradermal group showed significantly greater improvement, with a mean difference in pain score reduction of 1.6 points (95% CI: 0.57 to 2.67, P=0.003) compared to the subcutaneous group. For dysfunction scores, the intradermal group demonstrated immediate post-treatment benefits (mean difference: 9.4 points, 95% CI: 1.36 to 17.44, P=0.02), with sustained improvement at the one-month post-treatment follow-up (mean difference: 15.5 points, 95% CI: 7.95 to 23.01, P<0.001). Repeated measures ANOVA showed that pain and dysfunction scores significantly changed over time in both groups (P<0.001). Conclusion: Both subcutaneous and intradermal mesotherapy appeared to be effective short-term treatments for patients with KOA. However, intradermal mesotherapy demonstrated greater effectiveness at the one-month follow-up, with superior pain reduction and functional improvement compared with subcutaneous mesotherapy.
