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

Remote ischemic preconditioning (RIPC) represents a clinically feasible method for safeguarding vital organs against ischemic injury. However, its specific role in cerebral ischemia-reperfusion (I/R) injury remains to be definitively elucidated. In this study, we investigated the neuroprotective effects of RIPC on mice at 7 days post-cerebral I/R and its involvement in mitophagy and mitochondrial dysfunction. Cerebral I/R led to impaired brain function, as well as structural and functional damage to mitochondria. Notably, RIPC treatment ameliorated the neurological dysfunction induced by cerebral I/R. Compared with the I/R group, the expression levels of NeuN, MBP, PDH, and Tom20 were significantly elevated in the RIPC + I/R group. Furthermore, mitochondria in the RIPC + I/R group exhibited more intact structure compared to those in the I/R group. In mice subjected to I/R injury, RIPC treatment markedly increased ATP content, ADP content, TAN level and glucose uptake while upregulating expression levels of Parkin, Pink1 and P62 proteins; it also reduced both the volume of ischemic foci and the number of mitochondrial autophagosomes along with decreasing LC3B II/I ratio. In conclusion, RIPC may exert a neuroprotective role by inhibiting excessive mitophagy during subacute stages following an ischemic stroke.
