Physiological activities of the combination of fish oil and α-lipoic acid affecting hepatic lipogenesis and parameters related to oxidative stress in rats.

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
purposeWe studied the combined effect of fish oil and α-lipoic acid on hepatic lipogenesis and fatty acid oxidation and parameters of oxidative stress in rats fed lipogenic diets high in sucrose. A control diet contained a saturated fat (palm oil) that gives high rate of hepatic lipogenesis.
methodsMale Sprague-Dawley rats were fed diets supplemented with 0 or 2.5 g/kg α-lipoic acid and containing 0, 20, or 100 g/kg fish oil, for 21 days.
resultsα-Lipoic acid significantly reduced food intake during 0-8 days but not the later period of the experiment. Fish oil and α-lipoic acid decreased serum lipid concentrations and their combination further decreased the parameters in an additive fashion. The combination of fish oil and α-lipoic acid decreased the activity and mRNA levels of hepatic lipogenic enzymes in an additive fashion. Fish oil increased the parameters of hepatic fatty acid oxidation enzymes. α-Lipoic acid appeared to antagonize the stimulating effects of fish oil of fatty acid oxidation through reductions in the activity of some fatty acid oxidation enzymes. α-Lipoic acid attenuated fish oil-dependent increases in serum and liver malondialdehyde levels, and this compound also reduced the serum 8-hydroxy-2'-deoxyguanosine level. α-Lipoic acid affected various parameters related to the antioxidant system; fish oil also affected some of the parameters.
conclusionsThe combination of fish oil and α-lipoic acid effectively reduced serum lipid levels through the additive down-regulation of hepatic lipogenesis. α-Lipoic acid was effective in attenuating fish oil-mediated oxidative stress.
