Dear Editor,

The authors welcome the constructive comments from Kara et al. concerning our recent paper (Lees et al. 2019). Their primary observations relate to the absence of gender from our analyses, the clinical relevance of our regression models, and use of non-specific muscle quality (MQ) cut-points. In the first instance, it is imperative to point out that we do not disagree in principle with any of the points raised; however, we believe that we have either addressed or alluded to the related issues within the main manuscript.

The purpose of this pilot study was to highlight the importance of MQ as a conjunctive measure alongside established sarcopenia definitions. We agree with Kara et al. that reductions in muscle power and physical performance precede a decrease in muscle mass. This is why we included measures of upper and lower body strength alongside the assessment of muscle mass in our study design. Furthermore, we sought to investigate the utility of MQ given the recent...
