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
backgroundBoth Fms-like tyrosine kinase 3-internal tandem duplication (FLT3-ITD) and Additional Sex Comb-like 1 (ASXL1) mutations are frequent and early genetic alteration events in acute myeloid leukemia (AML) patients. These genetic alterations may be associated with an unfavorable prognosis.
objectiveUp to our knowledge, this is the first study performed to evaluate the clinical implication and prognostic significance of FLT3-ITD and ASXL1 mutations and their coexistence on the outcome of Egyptian AML patients.
methodsOur study included 83 patients with AML who were subjected to immunophenotyping and detection of FLT3-ITD and ASXL1 gene mutation by polymerase chain reaction (PCR) and real-time PCR, respectively.
resultsFLT3-ITD and ASXL1 mutations were detected in 20.5% and 18.1% of AML patients respectively. Seven patients (8.4%) had co-expression of both genes' mutations. FLT3-ITD mutation was significantly higher in younger age, higher WBCs count and poor cytogenetic risk patients (P= 0.01, < 0.001 and 0.008 respectively). ASXL1 mutation was significantly higher in intermediate cytogenetic risk patients (P= 0.2). The mean period of survival and relapse-free survival (RFS) were significantly reduced in FLT3-ITD and ASXL1 mutations compared with their non-mutant types (P= 0.01 and 0.03 respectively). Both mutations were independent risk factors for overall survival (OS) and (RFS) in univariate and multivariate analysis in AML patients.
conclusionFLT3-ITD and ASXL1 gene mutations or their coexistence can predict a poor prognosis in AML patients.
