Table 2_Measurement properties of the SARC-T: test-retest reliability, agreement and minim

A methodological test-retest study of the Sarcopenia Optoelectronic Chair-Rise Velocity Test (SARC-T) in 55 institutionalized older adults with sarcopenia. The dataset contains measurement properties including intraclass correlation coefficients, standard error of measurement, and minimal detectable change. The data was published by Blanca Pedauyé-Rueda on figshare in 2026.

Use Cases

• Validate the reliability of the SARC-T instrument based on reported ICC and CCC values.
• Calculate measurement error for chair-rise velocity in clinical studies based on the standard error of measurement (SEM).
• Interpret longitudinal changes in physical function based on the reported minimal detectable change (MDC95).
• Assess agreement and bias in repeated clinical measurements using the provided Bland-Altman analysis parameters.

Strengths

• Dataset reports specific reliability metrics: ICC = 0.93 and CCC = 0.93.
• Provides concrete measurement error values: SEM = 0.017 m/s and MDC95 = 0.05 m/s.
• Study conducted under standardized conditions with a specific population of 55 institutionalized older adults with sarcopenia.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects a specific population bias, being limited to institutionalized older adults with sarcopenia.
