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

backroundWhile low-carbohydrate/high-protein diets are common for rapid weight loss, their controversial side effects warrant investigation.

aimsThis study aimed to examine age- and duration-dependent effects of high-protein diets on the liver and kidneys of adult (6 months) and elderly (18 months) rats.

methodsThirty-two male Wistar albino rats were divided into four groups: Adult Standard, Adult High-Protein, Elderly Standard, and Elderly High-Protein. After one month, we collected kidney and liver samples for histological analysis and biochemical assessment of MDA and GSH levels. 

resultsHigh-protein diets severely affected the kidneys of both adult and elderly rats. The livers also exhibited moderate degenerative changes. We found a significant increase in MDA levels, indicating lipid peroxidation. Additionally, hepatic and renal GSH levels significantly increased in elderly rats on a high-protein diet, suggesting a metabolic response to oxidative stress. 

conclusionOur findings suggest that high-protein diets should be applied very cautiously, especially in elderly individuals and those with existing kidney disorders.
