Exploring the Effect of Preamputation Employment and Income on Ambulation in Dysvascular Lower Extremity Amputees After Amputee Rehabilitation: A Retrospective Cohort Study
Bibliographic record
Abstract
Objective To assess the relationship between 2-minute walk test (2MWT) distance, employment status, and median household income in adult dysvascular amputee patients after a 6-week rehabilitation program. Design Retrospective cohort study. Setting Amputation rehabilitation program. Participants In total, 505 patients were included in the analysis. Most (71.1%) were men and had below-knee amputations (78.3%); the average age was 65.3±11.6 years. Interventions Not applicable. Main Outcome Measures 2MWT distance at discharge. Results Men ( 68.3±32.6m) and below-knee amputation amputees (70.9±32.0m) walked significantly further than women ( 58.8±30.0m; P =.003) and above-knee amputees ( 47.2±25.7m; P <.001), respectively. A significant negative correlation was found between 2MWT distance and age ( r =−.32; P <.001) as well as time from consultation to admission ( r =−.23; P <.001). An unadjusted general linear model (GLM) revealed that employment status (F 2,446 =17.47; P <.001) but not income (F 4,446 =.714; P =.58) was statistically significantly associated with 2MWT distance. An adjusted (age, sex, time from consult to admission, and amputation level) GLM revealed employment status remained significant (F 2,434 =5.59; P =.004) and income remained insignificant (F 4,434 =.43; P =.784). Differences in 2MWT distance between employment and income groups did not meet clinical significance. Conclusions Preamputation employment appears to be associated with postrehabilitation outcomes.

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.
