Review Reports

Round 1

Reviewer 1 Report

This study included the polysomnographic results of 62 patients evaluated for OSA. Heart rate variability has been reported in OSA. The authors evaluated this variability using frequency and time domains. 

Major changes: the association of time and frequency domains with OSA was evaluated. However, the impact of hypoxemia and arousals was not included in the analysis. If unable to provide this data, the probability that arousals (and associated sympathetic activation) and not AHI could drive variability should be included in the discussion.

Minor changes: report the definition used for hypopneas in the AHI.

In table 1, please clarify how data is presented i.e. (mean+- SD)

Table 2, please clarify that p value is reported in parenthesis.
