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.

Abstract
introductionThe Alliance A041202/CCTG CLC.2 trial demonstrated superior progression-free survival with ibrutinib-based therapy compared to chemoimmunotherapy with bendamustine-rituximab (BR) in previously untreated older patients with chronic lymphocytic leukemia. We completed a prospective trial-based economic analysis of Canadian patients to study the direct medical costs and quality-adjusted benefit associated with these therapies.
methodsMean survival was calculated using the restricted mean survival method from randomization to the study time-horizon of 24 months. Health state utilities were collected using the EuroQOL EQ-5D instrument with Canadian tariffs applied to calculate quality-adjusted life years (QALYs). Costs were applied to resource utilization data (expressed in 2019 US dollars). We examined costs and QALYs associated ibrutinib, ibrutinib with rituximab (IR), and BR therapy.
resultsA total of 55 patients were enrolled; two patients were excluded from the analysis. On-protocol costs (associated with protocol-specified resource use) were higher for patients receiving ibrutinib (mean $189,335; P < 0.0001) and IR (mean $219,908; P < 0.0001) compared to BR (mean $51,345), driven by higher acquisition costs for ibrutinib. Total mean costs (over 2-years) were $192,615 with ibrutinib, $223,761 with IR, and $55,413 with BR (P < 0.0001 for ibrutinib vs. BR and P < 0.0001 for IR vs. BR). QALYs were similar between the three treatment arms: 1.66 (0.16) for ibrutinib alone, 1.65 (0.24) for IR, and 1.66 (0.17) for BR; therefore, a formal cost-utility analysis was not conducted.
conclusionsDirect medical costs are higher for patients receiving ibrutinib-based therapies compared to chemoimmunotherapy in frontline chronic lymphocytic leukemia, with the cost of ibrutinib representing a key driver.
