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.

2 · The registry

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

T-cell acute lymphoblastic leukemia (T-ALL) results from leukemic transformation of T-cell precursors arrested at specific differentiation stages, including an 'early-cortical' thymic maturation arrest characterized by expression of cytoplasmic TCRβ but no surface T-cell receptor (TCR) and frequent ectopic expression of the TLX1/3 NK-like homeotic proteins (NKL). We designed a TCRα VJC PCR to identify clonal TCRα rearrangements in 32% of 127 T-ALLs, including 0/52 immature/TCRγδ lineage cases and 41/75 (55%) TCRαβ lineage cases. Amongst the latter, TCRα rearrangements were not identified in 30/54 (56%) of IMβ/pre-αβ early-cortical T-ALLs, of which the majority (21/30) expressed TLX1/3. We reasoned that the remaining T-ALLs might express other NKL proteins, so compared transcript levels of 46 NKL in T-ALL and normal thymic subpopulations. Ectopic overexpression of 10 NKL genes, of which six are unreported in T-ALL (NKX2-3, BARHL1, BARX2, EMX2, LBX2 and MSX2), was detectable in 17/104 (16%) T-ALLs. Virtually all NKL overexpressing T-ALLs were TCRα unrearranged and ectopic NKL transcript expression strongly repressed Eα activity, suggesting that ectopic NKL expression is the major determinant in early-cortical thymic T-ALL maturation arrest. This immunogenetic T-ALL subtype, defined by TCRβ VDJ but no TCRα VJ rearrangement, is associated with a favorable outcome in GRAALL-treated adult T-ALLs.
