Dose-dependent Pharmacological Response to Rituximab in the Treatment of Antineutrophil Cytoplasmic Antibody-associated Vasculitis.
Article in The Journal of rheumatology, 2021. 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
objectiveRituximab (RTX) is effective in the induction and maintenance of remission in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). However, uncertainty remains regarding the optimal maintenance dosing regimen. This work evaluates the relationship between variability in RTX dosing and pharmacological response in AAV.
methodsA prospective cohort of patients with AAV (n = 28) with either granulomatosis with polyangiitis (n = 23) or microscopic polyangiitis (n = 5) receiving maintenance RTX therapy were followed in a single tertiary care academic medical center over a 2-year period. Patient demographics, RTX dosing information, and trough plasma RTX levels were collected along with laboratory measures of pharmacologic response, including B cell counts and ANCA titers.
resultsRTX dosing information from 94 infusions with 59 trough samples were collected with a mean ± SD dose of 640 ± 221 mg, dosing interval of 210 ± 88 days, and trough plasma RTX concentration of 622 ± 548 ng/mL. RTX trough concentrations were associated with RTX dose (ρ = 0.60,
conclusionRTX maintenance dosing of 500 mg every 6 months may be inadequate to maintain B cell depletion in the treatment of AAV.
