1 · What the graph read from it

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.

2 · The registry

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

backgroundMethotrexate (MTX) commonly used in rheumatoid arthritis (RA) has severe adverse effects. Ortho-vanillin, an inhibitor of Toll-like receptors (TLR), can prevent inflammation. Glucan is a cereal fiber recognized by dectin-1 or β-glucan receptors of phagocytic macrophages. The purpose of the current project was to study the effect of co-administration of MTX and vanillin by targeted delivery to macrophages using β-glucan microspheres to reduce inflammation of RA.

methodsMTX and vanillin nanoparticles in bovine serum albumin (BSA) or gelatin were doped in glucan particles (GPs) and characterized for their physical properties. Twenty-four hours after induction of RA in paw of rats, they received normal saline (1 mg/kg, ip), MTX (2 mg/kg/week, ip), β-glucan (1 mg/kg/week, ip), GPs-MTX (2 mg/kg/week, ip), GPs-vanillin (200 mg/kg/day, po), and GPs-MTX (2 mg/kg/week, ip) plus GPs-vanillin (200 mg/kg/day, po). The last group received free MTX ip and vanillin po for 14 days. Then, joint diameters, TNF-α and IL-6, were evaluated in rats.

resultsThe particle size of the GPs was 5.3 µm. MTX loading efficiency in glucan microspheres was 64.5% and vanillin 44.2%. The microspheres released 88.7% of MTX and 95.1% of vanillin over 24 h. The results of in vivo studies showed a significant reduction in paw volume, TNF-α and IL-6 (p < 0.05) in animals treated with combination of MTX and vanillin-doped glucan microspheres compared to the mixture of the two drugs in free form or each drug alone.

conclusionsCo-administration of MTX and vanillin-doped GPs may be more effective than MTX alone in RA.
