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
objectiveAberrant antigen expression was reported to be due to genetic and epigenetic dysregulation. This study aimed to address aberrant antigen expression and its link to poor prognostic genetic markers in acute leukemia patients.
methodsThis study included 432 newly diagnosed acute leukemia patients (AML, B-ALL). For all included patients blast cells expression for line assignment CD33 CD13 on B-All and CD7 on cytogenetically normal-AML blasts was assessed by flow cytometry in parallel to FLT3 and Philadelphia and philadelphia like chromosome in B-ALL.
resultsFrom the total 432 cases of acute leukemia, the most frequent aberrant antigen expressed in B acute lymphoid leukemia (ALL) was CD33 (23.3%) followed by CD13(16.7%); while the most frequent one in AML was CD7 (16.7%). Aberrant myeloid phenotype in B-ALL was associated with lower mean total leukocytes count (TLC), low platelets count, positive Philadelphia like chromosome, shorter overall survival compared to the B-ALL without. Aberrant lymphoid phenotype (CD7) in AML was associated with a higher platelets count, FLT3 mutation, shorter disease-free and overall survival compared to those patients without.
conclusionCD7 aberrant antigen expression is frequently detected in patients with CN-AML and frequently associated with FLT3 mutation. While in patients with B-ALL the most frequently detected ones are CD33 and CD13 which are frequently associated with Philadelphia like chromosome.
