Practical Research Methods for Orthopaedic Surgeons
Bibliographic record
Abstract
Inherent to understanding an orthopaedic study is a fundamental knowledge of the study's design principles and statistics. Statistics, in part, allow a researcher to sample a portion of the population and use probability to decide whether the findings from the sample are likely to apply to the whole population. Although statistical jargon can be confusing, several simple principles guide the approach to research design. It is helpful for orthopaedic surgeons to review different study designs and their levels of evidence, to understand statistical jargon and the selection of the statistical test that is appropriate for given types of data, and to be familiar with the process of sample size calculations. Knowledge gained from statistical principles and research design is used to interpret study results. Such knowledge is invaluable for judging the value of new clinical evidence and for designing future studies.

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, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
