<p>Overview of statistical analysis plan.</p>

Daniel Hickey's statistical analysis plan outlines a prospective observational cohort study of up to 160 patients undergoing Total Knee Arthroplasty at Beacon Hospital in Dublin, Ireland. The plan details the collection of continuous Garmin Vivosmart 5 wearable data and periodic Patient-Reported Outcome Measures (PROMs) from pre-operation to 6 months post-operation. It was last updated on April 15, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Model longitudinal trends in daily step count based on the described minute-level wearable data collection.
• Analyze correlations between wearable-derived mobility metrics and the Oxford Knee Score (OKS) as outlined in the primary analysis.
• Investigate associations between daily step count, pain ratings, and EQ-5D-5L scores using the described Spearman-type correlation methods.
• Study the integration of clinical indicators (e.g., BMI, prehabilitation participation) with PROMs and activity data for personalized rehabilitation insights.

Strengths

• Plan is based on a prospective cohort study design with a defined target of up to 160 participants.
• Describes integration of three data streams: continuous wearable data, multiple PROMs, and electronic health records.
• Specifies a clear temporal scope from four weeks pre-operatively to six months post-operatively.

Limitations

• The dataset is a 9.5 KB analysis plan (XLS), not the underlying patient data, which limits direct analytical use.
• Column-level documentation for the actual study data is absent; field semantics must be inferred from the plan.
• Row count for the actual observational data is unknown, which may limit suitability assessment for modeling.
