Hematological characteristics, cytogenetic features, and post-induction measurable residual disease in thymic stromal lymphopoietin receptor (TSLPR) overexpressed B-cell acute lymphoblastic leukemia in an Indian cohort.
Observational study in Annals of hematology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
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
The overexpression of cytokine receptor-like factor-2 (CRLF2) identified by anti-thymic stromal lymphopoietin receptor/TSLPR flow cytometry (FCM) has been reported as a screening tool for the identification of BCR-ABL1-like B-cell acute lymphoblastic leukemia/B-ALL with CRLF2 re-arrangement. TSLPR expression was studied prospectively in consecutive 478 B-ALLs (≤ 12 years (n = 244); 13-25 years (n = 129); > 25 years (n = 105)) and correlated with various hematological parameters and end-of-induction measurable residual disease (day 29; MRD ≥ 0.01% by 10-color FCM). TSLPR positivity in ≥ 10% leukemic cells was detected in 14.6% (n = 70) of B-ALLs. CRLF2 re-arrangement was detected in eight cases (11.4%) including P2RY8-CRLF2 (n = 6), and IgH-CRLF2 (n = 2) with a median TSLPR positivity of 48.8% and 99% leukemic cells, respectively. Recurrent gene fusions/RGF (BCR-ABL1 (17.1%); ETV6-RUNX1 (4.2%), TCF3-PBX1 (1.4%)), other BCR-ABL1-like chimeric gene fusions/CGFs (PDGFRB-rearrangement (2.9%), IgH-EPOR (1.4%)), CRLF2 extra-copies/hyperdiploidy (17.1%), and IgH translocation without a known partner (10%) were also detected in TSLPR-positive patients. CD20 positivity (52.9% vs 38.5%; p = 0.02) as well as iAMP21 (4.3% vs 0.5%; p = 0.004) was significantly more frequent in TSLPR-positive cases. TSLPR-positive patients did not show a significantly higher MRD, compared to TSLPR-negative cases (37% vs 33%). Increasing the threshold cut-off (from ≥ 10 to > 50% or > 74%) increased the specificity to 88% and 100% respectively in identifying CRLF2 translocation. TSLPR expression is not exclusive for CRLF2 translocations and can be seen with various other RGFs, necessitating their testing before its application in diagnostic algorithms. In patients with high TSLPR positivity (> 50%), the testing may be restricted to CRLF2 aberrancies, while patients with 10-50% TSLPR positivity need to be tested for both CRLF2- and non-CRLF2 BCR-ABL1-like CGFs.
