Abstract

fetched live from OpenAlex

Background: Decreased bone mineral density (BMD) is a concern in patients with Congenital Adrenal Hyperplasia (CAH) due to lifelong glucocorticoid replacement. Studies till date have yielded conflicting results. We wanted to systematically evaluate the available evidence regarding BMD in adult patients with CAH. Methods: We searched Medline, Embase and Cochrane Central Register of Controlled Trials to identify eligible studies. Studies comparing BMD in CAH patients with age- and sex-matched controls were included. Age less than 16 years and absence of controls were exclusion criteria. Two authors independently reviewed abstracts, read full-text articles, extracted data, assessed risk of bias using Newcastle-Ottawa scale and determined level of evidence using Grading of Recommendations Assessment, Development and Evaluation methodology. Results: Nine case-control studies with a total sample size of 598 (cases n=254, controls n=344) met eligibility criteria. Total body BMD (Mean Difference [MD]-0.06; 95%CI -0.07, -0.04), lumbar spine BMD (MD -0.05; 95%CI -0.07, -0.03) and femoral neck BMD (MD -0.07; 95%CI -0.10, -0.05) was lower in cases compared to controls. Lumbar spine T-scores (MD -0.86; 95%CI -1.16, -0.56) and Z-scores (MD -0.66; 95%CI -0.99, -0.32) and femoral neck T-scores (MD -0.75 95%CI -0.95, -0.56) and Z-scores (MD -0.27 95%CI -0.58, 0.04) were also lower in cases compared to controls. No clear correlation between BMD and glucocorticoid dose was found. Conclusion: BMD in adult patients with CAH was lower compared to controls. Although no clear dose-response relationship between glucocorticoid dose and BMD was found, it would be prudent to avoid over-treatment with glucocorticoids.

Full frame distilled prediction

Teacher imitation

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.
