Abstract
Objective To determine the prevalence of positive HBsAg in adults in rual Deqing, Zhejiang Province of China. Methods A cross-sectional study was carried out in four rural communities in Deqing County, Zhejiang Province, China. A toal of 4 434 subjects aged 18 to 64 years old participated in the questionnaire study, provided a 5 mL blood specimen and had a satisfactory measure of HBsAg. HBsAg was measured by ELISA. The Student t test was used for continuous variables such as age and the Chi-square test for category variables such as the prevalence in SPSS 11.0. Results The crude prevalence of positive HBsAg was 7.3%. The age-standardized prevalence was 8.0% and was significantly higher in men than in women (8.8% vs 6.2%, χ2=10.52, P=0.001). Conclusions The prevalence of positive HBsAg in adults aged 18 to 64 years old in rual China was high.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
