Reply to the Letter to Editor

We read with great delight the letter concerning our recently published systematic review and meta-analysis on frailty and clinical outcomes in heart failure.1 First, we thank the authors for reading our manuscript in detail and for expressing their critical comments. Second, these authors should be commended for going to great lengths seeking responses from the authors of the original studies. Third, their use of 6 colors (excluding black) in their Table 1 facilitated the readership for understanding the different aspects of their text.
