The Influence of Different Degrees of Energy Restriction on Bone Parameters in Young Female Rats.
Article in Calcified tissue international, 2025. 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 present study aimed to determine the influence of different degrees of energy restriction (ER) on the bones in young female rats. Forty female Sprague-Dawley rats (n = 40; age, 6 weeks) were randomly divided into the following five experimental groups after a 1-week acclimatization period: 0% ER, 10% ER, 20% ER, 30% ER, and 40% ER groups. The experimental period was 10.5 weeks. Statistical analysis was conducted using one-way analysis of variance, Tukey's post hoc comparison tests, and simple linear regression analysis. The body weight and fat weight showed significantly lower values above 20% ER. The bone mineral content and bone mineral density of the tibia in the 30% ER group were significantly lower than those in the 10% and 20% ER groups, and those in the 40% ER group was significantly lower than those in the 0%, 10%, and 20% ER groups. The trabecular thickness, cortical bone volume, and cortical total volume in the 40% ER group were significantly lower than those in the 0% ER group. The serum levels of parathyroid hormone, bone-specific alkaline phosphatase, and tartrate-resistant acid phosphatase significantly increased with increasing degree of ER. However, the serum levels of leptin, carboxylated osteocalcin, and carboxylated osteocalcin / uncarboxylated osteocalcin significantly decreased with increasing degree of ER. Our findings showed that 30% or 40% ER resulted in lower bone mass and 40% ER impaired bone microstructure in young female rats. However, 10% or 20% ER did not affect these parameters.
