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
Acute myeloid leukemia (AML) is driven by a combination of genetic alterations and non-mutational mechanisms that disrupt normal hematopoiesis and support leukemic cell survival. While the mutational landscape of AML is well characterized, the non-genetic processes that sustain leukemic maintenance remain comparatively less understood. Using human AML cell lines and murine models of AML, we identify BCL2-associated transcription factor 1 (BCLAF1) as a key regulator of leukemic progression through control of mRNA processing. BCLAF1 physically associates with core spliceosome components and regulates alternative splicing, with a predominant effect on intron retention. We demonstrate that BCLAF1 is required for the productive splicing of activating transcription factor 4 (ATF4) mRNA, thereby sustaining ATF4 protein expression. Loss of BCLAF1 reduces ATF4 protein levels, leading to downregulation of metabolic target genes and disruption of
