A Framework for Anemia Differential Diagnosis in Paleopathology Incorporating Metric Methods.
Article in American journal of biological anthropology, 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
objectivesThis paper explores metric manifestations of anemia in crania undergoing growth and development using micro-CT imaging. It proposes a framework for assigning a most-likely diagnostic option for anemia, based on evaluating the parameters proposed in this study. MATERIALS AND
methodsSixty-eight orbits/frontal bones of individuals aged birth to 15 years from Quebecois and Dutch archaeological collections dating to the 18th and 19th centuries underwent micro-CT analysis. Individuals were visually assessed for skeletal manifestations of marrow hyperplasia within the internal marrow space using a scoring rubric. Bone microarchitecture measurements were used to calculate T-scores and identify individuals who displayed potential manifestations of marrow hyperplasia. Relative cortical thickness ratios of the frontal bone were calculated for 16 individuals. Error testing was performed for all evaluations.
resultsUsing the micro-CT analysis and our diagnostic framework, anemia was inferred in 16% (10/61) of the sample that was preserved well enough for the study. Trabecular separation T-scores were considered the most significant metric for evaluating anemia. Frontal bone ratios were regarded as less insightful due to the imaging technique used. Age had a significant effect on bone measurements, and high repeatability was seen across methods. DISCUSSION: In this study, recommendations for assigning a diagnostic option prioritize evaluating metric features strongly related to anemia through a biological approach that considers the etiology of marrow hyperplasia. Including a combination of metric and internal visual evaluation criteria provides clearer lines of evidence for the assessment of abnormal bone changes associated with anemia beyond the macroscopic evaluation of porous lesions.
