Conventional DMARDs therapy decreases disease activity and inflammation in newly diagnosed patients with rheumatoid arthritis by increasing FoxP3, Sema-3A, and Nrp-1 gene expression.
Article in Inflammopharmacology, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundSemaphorins are axonal guidance molecules involved in neural development and contribute to the regulation of various phases of the immune response. This study aimed to investigate the plasma levels of the pro-inflammatory cytokine interleukin-6 (IL-6) and the regulatory T (Treg) cell-related cytokine interleukin-10 (IL-10), as well as the gene expression levels of forkhead box P3 (FoxP3), Semaphorin-3A (Sema-3A), Neuropilin-1 (Nrp-1), Semaphorin-4A (Sema-4A), and Plexin-D1 (Plxn-D1), in the peripheral blood of newly diagnosed rheumatoid arthritis (RA) patients treated with conventional disease-modifying antirheumatic drugs (DMARDs) for 6 months compared with healthy controls.
methodsPeripheral blood samples were obtained from 40 newly diagnosed RA patients (before and after treatment) and 40 age- and sex-matched healthy subjects. The plasma concentrations of IL-6 and IL-10 were quantified via enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of FoxP3, Sema-3A, Nrp-1, Sema-4A, and Plxn-D1 were assessed via quantitative real-time PCR.
resultsCompared with those in the controls, the plasma IL-6 levels in the RA patients (both pre- and post-treatment) were significantly greater (P < 0.001). Compared with the pre-treatment levels, the plasma IL-6 levels decreased significantly after DMARD therapy (P < 0.05). Moreover, plasma IL-10 levels were significantly greater in post-treatment RA patients than in controls (P < 0.05). The gene expression of FoxP3, Sema-3A, and Nrp-1 was significantly lower in pre-treated RA patients than in controls (P < 0.001). Compared with that in pre-treatment RA patients, the gene expression of FoxP3, Sema-3A, and Nrp-1 in DMARDs-treated RA patients was strongly increased (P < 0.05, P < 0.01, and P < 0.01, respectively). There was a positive correlation between Sema-3A gene expression and the gene expression of FoxP3 (r = 0.292, P < 0.01) and Nrp-1 (r = 0.569, P < 0.0001).
conclusionConventional DMARDs therapy effectively reduces disease activity and inflammation in newly diagnosed RA patients by increasing FoxP3, Sema-3A, and Nrp-1 gene expression.
