Correlation of CD33 expression level with disease characteristics and response to gemtuzumab ozogamicin containing chemotherapy in childhood AML.
Trial report in Blood, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 73 papers, 1 of them a synthesis that pooled 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

Abstract
CD33 is expressed on the majority of acute myeloid leukemia (AML) leukemic blasts and is the target for gemtuzumab ozogamicin (GO), a toxin-conjugated anti-CD33 mAb. In the present study, we quantified the CD33 mean fluorescent intensity of leukemic blasts prospectively in 619 de novo pediatric AML patients enrolled in Children's Oncology Group GO-containing clinical trials and determined its correlation with disease characteristics and clinical outcome. CD33 expression varied more than 2-log fold; a median mean fluorescent intensity of 129 (range, 3-1550.07) was observed. Patients were divided into 4 quartiles, quartiles 1-4 (Q1-4) based on expression and disease characteristics and clinical response defined across quartiles. High CD33 expression was associated with high-risk FLT3/ITD mutations (P < .001) and was inversely associated with low-risk disease (P < .001). Complete remission (CR) rates were similar, but patients in Q4 had significantly lower overall survival (57% ± 16% vs 77% ± 7%, P = .002) and disease-free survival from CR (44% ± 16% vs 62% ± 8%, P = .022). In a multivariate model, high CD33 expression remained a significant predictor of overall survival (P = .011) and disease-free survival (P = .038) from CR. Our findings suggest that CD33 expression is heterogeneous within de novo pediatric AML. High expression is associated with adverse disease features and is an independent predictor of inferior outcome. The correlation between CD33 expression and GO response is under investigation. These studies are registered at www.clinicaltrials.gov as NCT00070174 and NCT00372593.
