Article in Blood, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT01715480 (Physiological Effect of Sulforaphane Obtained From Broccoli Sprouts Homogenates), which is not on this map. Cited by 197 papers, 1 of them a synthesis that pooled it.

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.

Abstract

Although individuals with homozygous sickle cell disease (HbSS) share the same genetic mutation, the severity and manifestations of this disease are extremely heterogeneous. We have previously shown that the microRNA expression in normal and HbSS erythrocytes exhibit dramatic differences. In this study, we identify a subset of HbSS patients with higher erythrocytic miR-144 expression and more severe anemia. HbSS erythrocytes are known to have reduced tolerance for oxidative stress, yet the basis for this phenotype remains unknown. This study reveals that miR-144 directly regulates nuclear factor-erythroid 2-related factor 2, a central regulator of cellular response to oxidative stress, and modulates the oxidative stress response in K562 cell line and primary erythroid progenitor cells. We further demonstrate that increased miR-144 is associated with reduced NRF2 levels in HbSS reticulocytes and with decreased glutathione regeneration and attenuated antioxidant capacity in HbSS erythrocytes, thereby providing a possible mechanism for the reduced oxidative stress tolerance and increased anemia severity seen in HbSS patients. Taken together, our findings suggest that erythroid microRNAs can serve as genetic modifiers of HbS-related anemia and can provide novel insights into the clinical heterogeneity and pathobiology of sickle cell disease.
