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

Highly active anti-retrovirus therapy (HAART) has been used to block the progression and symptoms of human immunodeficiency virus infection. Although it decreases morbidity and mortality, clinical use of HAART has also been linked to various adverse effects such as severe cardiomyopathy resulting from compromised mitochondrial functioning. However, the mechanistic basis for these effects remains unclear. Here, we demonstrate that a key component of HAART, 3ꞌ-azido-3ꞌ-deoxythymidine (AZT), particularly, its active metabolite AZT-triphosphate (AZT-TP), caused mitochondrial dysfunction, leading to induction of cell death in H9c2 cells derived from rat embryonic myoblasts, which serve as a model for cardiomyopathy. Specifically, treatment with 100µM AZT for 48h disrupted the mitochondrial tubular network via accumulation of AZT-TP. The mRNA expression of dynamin-related protein (Drp)1 and the Drp1 receptor mitochondrial fission factor (Mff) was upregulated whereas that of optic atrophy 1 (Opa1) was downregulated following AZT treatment. Increased mitochondrial translocation of Drp1, Mff upregulation, and decreased functional Opa1 expression induced by AZT impaired the balance of mitochondrial fission vs. fusion. These data demonstrate that AZT-TP causes cell death by altering mitochondrial dynamics.
