Na-AIP-1 secreted by human hookworms suppresses collagen-induced arthritis.
Article in Inflammopharmacology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Proteins from helminths have been posed as new immunomodulatory agents with exciting potential in the treatment of immune-mediated diseases including rheumatoid arthritis (RA). In this study we assess the effects of a helminthic excretory/secretory (ES) protein Na-AIP-1 as monotherapy and in combination with methotrexate (MTX) in the well-described collagen-induced arthritis (CIA) model of RA. CIA was induced in DBA/1 J mice which were treated after the onset of arthritis with Na-AIP-1 monotherapy, MTX or Na-AIP-1 + MTX. The clinical scores for weight, arthritis and paw width were recorded along with joint histology as outcome measures. For the clinical parameters of weight, paw score and paw width, none of the Na-AIP-1 monotherapy, MTX therapy or Na-AIP-1 + MTX combination therapy groups displayed any significant difference when compared to the arthritis control. However, a significant reduction in histological score was identified after both monotherapy (Na-AIP-1: 0.83 ± 0.24 vs Arthritis control: 5.58 ± 1.49, p = 0.0277) and combination therapy (Na-AIP-1 + MTX: 0.55 ± 0.28 vs Arthritis control: 5.58 ± 1.49, p = 0.0233) when compared to arthritis control. Furthermore, Na-AIP-1 as both monotherapy (Na-AIP-1: 0.83 ± 0.24 vs MTX: 5.73 ± 1.82 p = 0.0261) and combination therapy (Na-AIP-1 + MTX: 0.55 ± 0.28 vs MTX: 5.73 ± 1.82, p = 0.0221) also significantly reduced histological score when compared to MTX monotherapy. Na-AIP-1 significantly reduced joint pathology in CIA. The hookworm protein Na-AIP-1 seems to be effective in the treatment of RA as monotherapy and when dosed together with MTX, constituting a potential new candidate for drug development. Research should focus on elucidating the mechanism of Na-AIP-1 action as a means to identify novel targets for therapeutics and to further our current understanding of immunobiology in RA.
