Abstract
Background
Although the association between SARC-F questionnaire positivity and mortality has previously been studied, the results are inconsistent. Testing the predictive validity of the SARC-F questionnaire for clinically relevant outcomes of vital prognoses is important.
Aim
The objective of this study was to test the predictive validity of SARC-F by conducting a meta-analysis on the association between SARC-F, a screening tool for sarcopenia, and mortality.
Methods
This meta-analysis used the MEDLINE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and Google Scholar databases for literature searches. Studies that examined the relationship between SARC-F questionnaire positivity and mortality and reported hazard ratios or odds ratios and 95% confidence intervals were included. A random-effects model was used for statistical analyses, and pooled hazard ratios, pooled odds ratios, and 95% confidence intervals were calculated.
Results
Through the literature search, we found five studies (7501 individuals) that met the eligibility criteria for this study. The pooled hazard ratio for SARC-F questionnaire positivity and mortality was 1.87 (95% confidence interval 1.41–2.46; P < 0.001), indicating a significant association. The pooled odds ratio for SARC-F questionnaire positivity and mortality was 1.97 (95% confidence intervals 1.10–3.53; P = 0.02), showing a significant association.
Conclusions
There was a significant association between SARC-F positivity and future mortality, indicating the predictive validity of the SARC-F questionnaire.
