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

Acute lymphoblastic leukaemia (ALL) is a malignant proliferative disease that originates from B‑lineage or T‑lineage lymphoid progenitor cells. Resistance to chemotherapy remains an important factor for treatment failure. The aim of the present study was to investigate drug resistance in T‑cell ALL (T‑ALL). Bioinformatics analysis of Oncomine and Gene Expression Omnibus data was performed to evaluate the expression of haematopoietic SH2 domain containing (HSH2D) in various lymphomas. HuT‑78 cells with HSH2D overexpression and or knockdown were constructed, and the effect on related downstream signalling molecules was detected. To study the effect of HSH2D on methotrexate (MTX) resistance, cell cycle and apoptosis analyses were conducted using flow cytometry, and MTT and EdU assays were used to detect the effect of MTX resistance and HSH2D gene expression on the biological function of HuT‑78 cells. Via the analysis of the data sets, it was identified that the expression of HSH2D was downregulated in T‑ALL compared with B‑cell ALL. Western blotting and reverse transcription‑quantitative PCR demonstrated that the overexpression of HSH2 resulted in the inhibition of CD28‑mediated IL‑2 activation. In related experiments with drug‑resistant cell lines, it was determined that HSH2D expression is necessary for HuT‑78 cells to be resistant to MTX. In conclusion, the results suggested that HSH2D serves an important role in the resistance of T‑ALL to MTX, which provides a potential research target for the study of drug resistance of T‑ALL.
