Calcium carbonate supplementation exacerbated gut microenvironment disruption in senile osteoporosis mice.
Article in iScience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Calcium carbonate supplements are a fundamental component in the prevention and treatment of osteoporosis. However, doubts regarding their use in the management of senile osteoporosis have been on the rise. The intestinal microenvironment plays a crucial role in bone metabolism and mineral absorption. Nevertheless, it remains unclear whether oral calcium carbonate itself affects the intestinal microbiota, thereby influencing mineral absorption. Using senile osteoporosis mice with 16S rDNA sequencing, the study found calcium disrupted intestinal barrier. It slightly alleviated age-related bone loss but worsened gut dysbiosis, proinflammatory cytokine imbalance, and systemic inflammation. This study reveals that calcium carbonate supplements disrupt the intestinal microbial ecosystem, impair the intestinal mucosal barrier function, and exacerbate systemic inflammatory responses, resulting in minimal efficacy in the treatment of senile osteoporosis. This finding provides a perspective for understanding the potential trade-offs of calcium carbonate in the treatment and management of senile osteoporosis.
