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

Doxorubicin (DOX), is an indispensable first-line chemotherapeutic. Despite this first-line indication, clinical use of DOX is limited by severe, off-target, and often irreversible cardiotoxicity. DOX induces cytotoxicity in rapidly dividing cancer cells via inhibition of Topoisomerase IIα. However, the underlying mechanisms by which DOX causes cell death in non-replicative, terminally differentiated cardiomyocytes remain poorly understood. Emerging evidence suggests that mitochondrial uptake of DOX is contributory to cardiotoxicity. Whether mitochondrial stress pathways, including the mitochondrial unfolded protein response (UPR
