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

This study assesses the impact of sublethal levels of four marine toxins ciguatoxin (CTX-1), maitotoxin-2 (MTX-2), saxitoxin (STX) and brevetoxin-2 (BTX-2) on murine hepatic detoxification enzymes expressed in mouse liver. CTX-1, BTX-2, and STX altered hepatic detoxification responses, but their effects were generally more limited or temporally variable than those observed with MTX-2. CTX-1 produced time-dependent changes in cytochromes P450 (CYPs)-associated activities, BTX-2 induced early CYP1A2 and CYP3A11 responses followed by later suppression, and STX reduced CYP1A2 and CYP3A11 while increasing microsomal reductase activities. Of these toxins, MTX-2 exhibited the highest toxicity, notably decreasing key proteins such as CYPs, including CYP1A2 and CYP3A11. CYP enzymes are vital for metabolizing important endogenous and various xenobiotic substances, including therapeutic drugs. After MTX-2 exposure, both CYP1A2 and CYP3A11 levels dropped significantly at 12 h (
