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

Mitochondria are well known to produce ATP for cell energy requirements and thermogenesis simultaneously by the respiratory chain, with a potential optimum temperature of 50 °C, while deleterious overheating should be prevented by a yet unknown system. Here, we report the identification of a human Transient Receptor Potential Vanilloid 1 (mitoTRPV1) alternative isoform located in the mitochondrial inner membrane, which acts as a thermostat regulating mitochondrial maximal temperature. The ubiquitously expressed mitoTRPV1 open reading frame overlaps TRPV1 exons 1 and 2 and intron 2 in a + 1 frame, encoding for an effective 150 amino-acid N-terminal mitochondrial targeting sequence (MTS) conserved amongst mammalian species, followed by the 687 amino acids of the TRPV1 C-terminal sequence. Pharmacological activation of mitoTRPV1 induces a low cytoplasmic Ca
