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

objectivesThe effectiveness of TNF inhibitors in RA has been shown to be affected by obesity. No such effect has been found for abatacept and rituximab, while for tocilizumab results are ambiguous. Additionally, it remains unresolved whether sex is an effect modifier for obesity. We investigated the impact of obesity on the drug effectiveness of conventional synthetic or biologic DMARDs, taking into account potential sex-specific differences.

methodsData from 10 593 RA patients included in the German observational cohort study Rheumatoid Arthritis: oBservation of BIologic Therapy (RABBIT) since 2009 were analysed. Patients had to have a BMI ≥18.5 kg/m2, at least one follow-up and 6 months of observation time. The influence of obesity on drug effectiveness was investigated by regression analysis, adjusting for potential confounders.

resultsObesity had a negative impact on improvement in the DAS with 28 joints using ESR as an inflammation marker of -0.15 (95% CI: -0.26; -0.04) units for women receiving conventional synthetic DMARDs, -0.22 (95% CI: -0.31; -0.12) units for women receiving TNF inhibitors, -0.22 (95% CI: -0.42; -0.03) units for women receiving tocilizumab and -0.41 (95% CI: -0.74; -0.07) units for men receiving tocilizumab. Overall, no negative obesity effects on the effectiveness of rituximab and abatacept were found.

conclusionObesity has a negative impact on the effectiveness of cytokine-targeted but not cell-targeted therapies in daily practice, affecting more outcomes and therapies in women than in men. Overall, no effects of obesity on treatment effectiveness were found for rituximab and abatacept.
