Pilot measurement summary (public)
Gap 1 & Gap 2 · n = 63 · pre-extraction calibration
Public summary statistics from the PPCS aerobic pilot audit. No restricted links.
Summary for Foundation Stack readers (pilot calibration). This is not formal systematic-review pooling.
Gap 1 — adherence in Results
| Category | n | % |
|---|---|---|
| Truly objective | 11 | 17.5% |
| Truly not reported | 40 | 63.5% |
| Explicitly not measured | 8 | 12.7% |
| Subjective only | 4 | 6.3% |
Pseudo-objectivity gap: automated first pass flagged 41.3% as objective (hardware in Methods); manual verification left 17.5% truly objective — 23.8 percentage points.
Rule: hardware in Methods ≠ adherence reported in Results.
Gap 2 — recovery endpoints
| Finding | Count |
|---|---|
| Fully objective primary endpoint | 0 / 63 |
BCTT-class (partially_objective) |
10 / 63 (15.9%) |
| Symptom scales / composite / unclear | 53 / 63 |
Co-occurrence (largest cells)
- 24 / 63: no quantified adherence and unclear primary outcome structure
- 8 / 63: no adherence + BCTT-class primary measure
- 6 / 63: no adherence + symptom-scale primary
8 of 11 papers with truly objective adherence used a composite primary outcome.

Limitations
Pilot n = 63 convenience-complete PDFs; ~78 additional full texts pending. Patterns may change when the full aerobic corpus is coded.
