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.

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

Blinatumomab is an immunotherapy drug approved for the treatment of acute lymphoblastic leukemia. Since not all patients respond to blinatumomab, markers are needed to predict the efficacy of blinatumomab in individual patients. We hypothesized that the pre-treatment blast-to-lymphocyte ratio would predict blinatumomab efficacy. To examine this possibility, we conducted a post hoc analysis using data from the TOWER Clinical Trials (NCT02013167). Multivariate analysis showed that, along with the treatment groups, each of the following was independently correlated with superior progression-free survival: salvage-treatment phase, allogeneic stem cell transplantation, and pre-treatment ratio of bone marrow blasts-to-peripheral blood lymphocytes < 25.
