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

Histidinemia is an inherited metabolic disorder biochemically characterized by high concentrations of histidine in biological fluids. Usually affected patients are asymptomatic although some individuals have mental retardation and speech disorders. Considering the high prevalence of histidinemia and the scarce information on the effects of maternal histidinemia on their progeny, we investigated various parameters of oxidative stress in brain cortex and hippocampus of the offspring from female rats that received histidine (0.5 mg/g of body weight) in the course of pregnancy and lactation. At 21 days of age we found a significant increase of thiobarbituric acid reactive substances (TBARS), 2',7'-dihydrodichlorofluorescein oxidation, superoxide dismutase (SOD) activity, catalase (CAT) activity, total sulfhydryls and glutathione (GSH) content in cerebral cortex and hippocampus. We also verified that at 60 days of age, GSH, SOD and total sulfhydryls returned to normal levels in brain cortex, while the other parameters decreased in the same structure. In the hippocampus, at 60 days of age GSH returned to normal levels, CAT persisted elevated and the other parameters decreased. These results indicate that histidine administration to female rats can induce oxidative stress in the brain from the offspring, which partially recovers 40 days after breastfeeding stopped.
