Clinical significance of complex repetitive discharges: A case‐control study
Bibliographic record
Abstract
Complex repetitive discharges (CRDs) are a striking, infrequent finding on needle electromyography (EMG), but their significance is debated. This retrospective case-control study of 486 patients evaluated in a general hospital-based EMG laboratory examined the association of CRDs with specific diagnostic categories, duration of symptoms, and comorbid diabetes mellitus. No CRDs were identified in patients without other evidence of neuromuscular disease. Myopathy was associated with an increased risk of CRDs (adjusted odds ratio, 5.98; 95% confidence interval, 2.38 to 14.99). In general, neuropathic conditions were not associated with either an increased or decreased risk of CRDs compared with other neuromuscular diseases, although confidence intervals were wide. Similarly, neither the chronicity of symptoms nor the presence of diabetes yielded odds ratios that differed significantly from unity. In clinical populations similar to the one we studied, the positive predictive value of CRDs for any of the diagnoses we evaluated is low. However, the absence of CRDs can be of diagnostic value in that it reduces the likelihood of myopathy or motor neuron disease. The likelihood of finding CRDs in acute conditions is the same as that in chronic conditions.

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.
