Influence of age on biochemical serum parameters in female alpacas - A retrospective study.
Article in Heliyon, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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 determination of biochemical parameters plays an important role in the veterinary care of alpacas, as it can provide an overview of the integrity and function of various organs and metabolic states. Various reference intervals are available for interpreting biochemical results in alpacas, but physiological variations due to age, sex or season should also be considered. Particularly, information on the influence of age is scarce. In a retrospective study, we examined 17 measured and three calculated biochemical parameters of 21 healthy female alpacas from a research herd over a period of nine years. We found significant positive correlations between age and serum triglycerides, selenium, vitamin E, urea, urea/creatinine ratio, calcium/phosphate ratio and significant negative correlations between age and aspartate aminotransferase activity, calcium and phosphate. However, our results differ to some extent from those found in the literature comparing changes in biochemical parameters between juvenile and adult alpacas. Overall, our data suggest that some biochemical parameters in adult alpacas are subject to physiological changes with age, which should be considered when interpreting laboratory results in this species.
