BCL2L1 is associated with γ-globin gene expression.
Article in Blood advances, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
Fetal hemoglobin (HbF) expression is partially governed by the trans-acting quantitative trait loci BCL11A and MYB and a cis-acting locus linked to the HBB gene cluster. Our previous analysis of the Genotype-Tissue Expression database suggested that BCL2L1 was associated with HbF gene expression. In erythroid progenitors from patients with sickle cell disease, BCL2L1 messenger RNA (mRNA) levels were positively correlated with HBG mRNA and total HbF concentration (r2 = 0.72, P = .047 and r2 = 0.68, P = .01, respectively). Inhibition of BCL2L1 protein activity in HbF-expressing HUDEP-1 cells decreased HBG expression in a dose-dependent manner. Overexpression of BCL2L1 in these cells increased HBG expression fourfold (P < .05) and increased F cells by 13% (P < .05). Overexpression of BCL2L1 in erythroid progenitors derived from primary adult CD34+ cells upregulated HBG expression 11-fold (P < .05), increased F cells by 18% (P < .01), did not significantly affect cell differentiation or proliferation, and had a minor effect on survival. Although the mechanism remains unknown, our results suggest that BCL2L1 is associated with HbF gene activation.
