A methodological survey on reporting of pilot and feasibility trials for physiotherapy interventions: a study protocol
Bibliographic record
Abstract
INTRODUCTION: Pilot and feasibility trials aim to test whether a full trial can be conducted or if any procedures must be changed for the full trial. Pilot trials must be reported in a transparent, accurate and complete way. In this report, we present a protocol for a methodological survey with the following aims: (1) to determine the percentage of physiotherapy trial reports which claim to be pilot or feasibility trials that evaluate feasibility, (2) to determine the aspect of feasibility evaluated in the primary objectives of the pilot or feasibility trials, (3) to describe the completeness of reporting of abstracts and full articles of pilot or feasibility trials using the Consolidated Standards of Reporting Trials (CONSORT) extension to randomised pilot and feasibility trials and (4) to investigate factors associated with completeness of reporting of pilot or feasibility trials. METHODS AND ANALYSIS: Reports of randomised controlled trials indexed in the Physiotherapy Evidence Database (PEDro) that claim to be pilot or feasibility trials and published in 2011-2017 will be included. Two independent reviewers will confirm eligibility and classify the aspect of feasibility being evaluated in the objectives of the included pilot or feasibility trials. Completeness of reporting of both the abstract and the full article will be evaluated using the CONSORT extension to randomised pilot and feasibility trials. The primary analysis will be a descriptive analysis about the reporting quality of abstracts and full texts of pilot and feasibility trials. We will use generalised estimating equation analysis to explore factors associated with completeness of reporting. ETHICS AND DISSEMINATION: The results of this study will be disseminated by presentation at conferences and will be submitted for publication in a peer-reviewed journal. Ethical approval is not necessary for this study.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Direct model labels (unvalidated)
Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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, unvalidatedLabeled directly by 2 models reading the full record.
