Effects of Dietary Zinc Deficiency and Supplementation on Prepubertal Rat Testes: Sulfhydryl and Antioxidant Status.
Article in Indian journal of clinical biochemistry : IJCB, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The study was designed to investigate the effects of dietary zinc deficiency and supplementation on antioxidant system viz. superoxide-dismutase, glutathione reductase, glutathione peroxidase, glutathione- S-transferase, catalase and sulfhydryls levels (GSH, TSH, NPSH and PBSH) in testes of Wistar rats. Pre-pubertal rats were divided into two groups with 6 sub-groups each viz. zinc control (ZC), pair fed (PF), zinc deficient (ZD), zinc control supplementation (ZCS), pair-fed supplementation (PFS) and zinc deficient supplementation (ZDS). Experiments were set for 2- and 4-weeks followed by 4 weeks of zinc supplementation. The zinc deficient group animals exhibited significant decrease in gonado-somatic index (2- and 4- weeks), sulfhydryls levels, GSH, GPx, GR (2 and 4-weeks) and GST concentration (2-weeks). However, after zinc supplementation significant improvement in gonadosomatic index, SH, GSH, antioxidant enzyme levels (GR, GPx, and GST) in deficient groups has been observed. Zinc deficiency during pre-pubertal period affected growth and caused dysregulation of the glutathione antioxidant system. The significant alterations in the levels of antioxidant enzymes and non-enzymatic antioxidant system (GSH and SH) in zinc deficient groups could be due to alleviated generation of free radicals, causative factor for increased oxidative stress which may lead to infertility as oxidative stress is a common pathology seen during infertility. Altered antioxidant system and sulfhydryls levels in testes due to dietary zinc deficiency reflect the significance of optimum zinc for maintaining homeostatic balance in gonadal physiology. Supplementing zinc for 4 weeks could reduce the redox imbalance which may help in alleviating oxidative stress induced alterations in testes.
