Review in World journal of microbiology & biotechnology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04666649 (Pegcrisantaspase in Combination With Venetoclax for Treatment of Relapsed or Refractory Acute Myeloid Leukemia), which is not on this map. Cited by 45 papers.

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

L-asparaginase is a critical part of the treatment of acute lymphoblastic leukaemia in children and adolescents, and has contributed to the improvement in patient outcomes over the last 40 years. The main products used in clinical treatment are L-asparaginase enzymes derived from Escherichia coli and Erwinia chrysanthemi. However, a very active area of research is the identification and characterisation of potential new L-asparaginase therapeutics, from existing or novel prokaryotic and eukaryotic sources, including mutations to improve function. In this review, we discuss the critical factors necessary to adequately characterise novel L-asparaginase therapeutic products, including enzyme kinetic parameters, glutaminase activity, and toxicity. One critical consideration is to ensure that the substrate affinity of novel enzymes, as measured by the Michaelis constant K
