Abstract

fetched live from OpenAlex

BACKGROUND. Due to a growing concern with regard to the relationship between osteoporosis and fractures, we wished to examine the correlation of systemic bone density with lacrimal bone characteristics (thickness and density), as measured at the time of dacryocystorhinostomy (DCR). Significant correlation would suggest that oculoplastic surgeons may screen for osteoporosis during DCR. METHODS. A prospective study of the bone mineral density in patients (n=32) undergoing DCR was conducted. During DCR, the lacrimal bone thickness and density were estimated clinically. Postoperatively, the systemic bone density was measured by dual-energy x-ray absorptiometry (DEXA) scanning. The data were analyzed using Student's t-test, Pearson correlation and Pearson chi-square methods. RESULTS. Analyzed in a bivariate arrangement, significant correlation (p<0.05) was detected between the systemic bone density (as measured at two sites, the femoral head and lumbar spine) and the lacrimal bone characteristics (thickness and density). Therefore, the lower the lacrimal bone thickness or density, the lower the systemic bone density. INTERPRETATION. With the finding of significant correlation between lacrimal bone thickness and density and systemic bone density, oculoplastic surgeons can screen for osteoporosis during DCR. If low-density thin bone is encountered during DCR, the patient's general practitioner should be alerted.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
