Sustainable synthesis of hydroxyapatite from poultry waste for veterinary applications: A calcination approach.
Article in Open veterinary journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Background: Chicken eggshells and bone waste are waste materials rich in calcium (Ca) and phosphorus (P), and they are often discarded despite their potential value. These materials are promising precursors for hydroxyapatite (HA), a biocompatible material structurally similar to natural bone that is widely used in biomedical applications. Aim: To evaluate the Ca and P contents of broiler chicken eggshells and bone waste and to synthesize HA from these waste materials. The results highlight the potential of broiler chicken bones as a sustainable source of HA, particularly for veterinary bone graft applications. Methods: Eggshell and chicken bone waste samples were collected from restaurants. The samples were washed, cleaned, dried, and heated at 800°C to produce calcite. The resulting calcite suspension was synthesized by heating it at 70°C and gradually mixing it with an ammonium phosphate ((NH Results: The analysis revealed that eggshells contained 15.986 ± 0.188% Ca and 13.794 ± 0.176% P, whereas chicken bones had higher Ca and P levels, with 18.9 ± 0.386% Ca and 13.906 ± 0.320% P. The average Ca:P ratio was 1:1.158 for eggshells and 1:1.359 for chicken bones. Conclusion: This study demonstrates the feasibility of converting poultry industry waste into valuable biomaterials to promote sustainable practices. The higher Ca and P levels observed in chicken bones than in eggshells may offer superior potential for treating pet fractures.
