L-carnitine as a novel approach for pain and inflammation relief in rheumatoid arthritis.
Trial report in Inflammopharmacology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by joint inflammation, largely mediated by pro-inflammatory cytokines. Considering the established involvement of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway and transforming growth factor-beta1 (TGF-β1) in RA, this research aimed to assess efficacy and safety of L-carnitine as an adjunct therapy targeting these pathways. Forty-six patients with active RA were randomly divided into two equal groups. Group1 (control group) received disease-modifying antirheumatic drugs (DMARDs), including methotrexate, leflunomide, and hydroxychloroquine. Group2 (L-carnitine group) received, DMARDs plus L-carnitine 500 mg twice daily for 12 weeks. A clinical evaluation was conducted, which included tender joint count (TJC), swollen joint count (SJC), pain intensity quantified via the visual analogue scale (VAS), and morning stiffness duration. Additionally, the Disease Activity Score in 28 joints (DAS28) and functional capability as measured by a modified health assessment questionnaire (MHAQ) were assessed. Laboratory evaluation included C-reactive protein (CRP), STAT3, and TGF-β1 measurement. All evaluations were executed both at baseline and following a 12-week treatment period. After 12 weeks, the L-carnitine group showed significant improvement in morning stiffness, VAS, TJC, CRP, DAS28, and MHAQ compared to baseline. While no significant within-group changes were observed in STAT3, TGF-β1 in the L-carnitine group, STAT3 levels increased significantly in the control group compared to baseline. In conclusion, L-carnitine in combination with DMARDs may enhance clinical outcomes in RA by mitigating systemic inflammation. Nevertheless, its impact on STAT3 and TGF-β1 remains unclear and warrants further research.
