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
Induction of ferroptosis is a potential strategy to eliminate chemotherapy-resistant acute myeloid leukemia (AML) cells. Here, we investigate the role and mechanism of thyroid hormone receptor-associated protein 3 (THRAP3) in ferroptosis of AML cells. We show that high expression of THRAP3 is correlated with a poor prognosis in AML patients. THRAP3 knockdown suppresses AML cell proliferation, and delays orthotopic and subcutaneous tumor growth in male mice; however, THRAP3 overexpression exerts the opposite roles. THRAP3 overexpression promotes resistance of AML cells to RSL3/erastin-induced ferroptosis via inhibiting iron accumulation and promoting GSH synthesis. Mechanistically, THRAP3 recruits SLU7 homolog, splicing factor (SLU7) to facilitate GIT ArfGAP 2 (GIT2) Exon14 skipping. Inhibition of GIT2 Exon14 skipping reverses THRAP3-induced ferroptosis resistance in vitro and in vivo. Altogether, THRAP3 contributes to ferroptosis resistance of AML cells via interaction with SLU7 to trigger GIT2 Exon14 skipping, which suggests THRAP3 to be a therapeutic target for AML.
