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.
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
Arachidonic acid, the most abundant polyunsaturated fatty acid in rat liver nuclei phospholipids is a major target of free radical attack, which induces lipid peroxidation. The non-enzymatic lipid peroxidation process in intact rat liver nuclei and in several chromatin fractions indicated that the most sensitive fatty acid for peroxidation is arachidonic acid C20:4 n-6. In this study, the effect of different amounts of arachidonic acid hydroperoxide on the lipid peroxidation of rat liver nuclei and chromatin fractions was studied; rat liver nuclei and chromatin fractions deprived of exogenous added hydroperoxide were utilized as control. The addition of arachidonic acid hydroperoxide to liver nuclei produces a marked increase in light emission that was hydroperoxide concentration dependent. The maximal peak of chemiluminescence displayed by the different chromatin fractions analyzed was observed between 20 and 80 min of incubation. The highest value of light emission was displayed by the high-density chromatin fractions, the 27.5 K fraction showed intermediate values of light emission, whereas the lowest density fraction produced very low chemiluminescence. A high correlation between arachidonic acid hydroperoxide concentration and chemiluminescence in the different chromatin fractions was observed.
