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.

Abstract

abstractFanconi anemia (FA) is a rare inherited disorder characterized by progressive bone marrow failure (BMF) and a predisposition to malignancy. Systemic reactive oxygen species (ROS) and increased sensitivity of FA hematopoietic progenitors to ROS play a key role in the pathogenesis of BMF. Treatment with antioxidants improve hematopoietic function in Fancc-/- mice. We report the safety, tolerability, and pharmacokinetics of quercetin, a naturally occurring antioxidant in the first dose-finding phase 1 study for patients with FA. Twelve patients (median age, 7 years [range, 3-21]) received oral quercetin twice daily for 4 months. Quercetin was well tolerated at all dose levels. Allometrically bodyweight-adjusted dose with a maximum adult daily dose of 4000 mg/d was established as the recommended dose of quercetin. Patients in an expansion cohort (n = 18) were treated using this recommended dose for 6 months. A subset of patients showed reduced ROS levels in the peripheral blood (PB) and bone marrow stem cell compartment. Patients in the analysis cohort treated with the recommended dose of quercetin achieved an a priori-defined optimal response of 25% reduction in the PB ROS level compared with baseline. Platelet counts remained stable to slightly improved over the study period (P = .06). Absolute neutrophil counts (P = .01) and hemoglobin levels gradually declined (P = .001). In those with evidence of BMF at baseline, 8 of 15 patients (53%) had a hematological response at some point after quercetin treatment. Fluctuations in counts are common in patients with FA, limiting accurate assessment of the impact of quercetin use in FA. This trial was registered at www.ClinicalTrials.gov as #NCT01720147.
