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

The shark bile alcohol, 5β-scymnol, protects mice from the hepatotoxic effects of paracetamol (APAP) overdose. To elucidate the hepatoprotective structural moiety of scymnol, we compared its effect with that of its analogue and natural bile salt, sodium scymnol sulfate, in a clinically relevant model of APAP-induced toxicity. Exposure of healthy male Swiss mice to a toxic overdose of APAP (350 mg/kg, ip) significantly increased serum hepatocellular enzyme activities, decreased hepatocellular glutathione (GSH) levels, and induced severe centrilobular hepatocellular necrosis. Repeated low-dose scymnol (5 mg/kg/day for 7 days, ip) significantly reduced the extent of APAP-induced hepatotoxicity without preventing GSH depletion. Sodium scymnol sulfate, which lacks the tri-hydroxyl-substituted aliphatic side chain of scymnol, failed to reduce the APAP hepatotoxicity or prevent GSH depletion when tested under the same experimental conditions. We conclude that the tri-hydroxyl-substituted aliphatic side chain is the hepatoprotective structural moiety of 5β-scymnol that suppresses APAP-induced cytotoxicity in mice.
