Specific comments: On the first page of the introduction, line 23, the authors state: Yung et al. (2014) developed a distinctive dose using anterior-to-posterior pressures (AP) of the cervical spine that resulted in a reduction in systolic blood pressure (SBP) and heart rate (HR), My reading of this article suggests that the only significant differences were in HR which the authors suggest in their comments was the rationale for the use of BP in their power calculation. Response: We deleted the phrase “systolic blood pressure (SBP),” and have revised the statement so that it now reads: “…using anterior-to-posterior pressures (AP) of the cervical spine that resulted in a reduction in heart rate (HR),…” Line 44, the authors cite Egwu 2009…show more content…
This does not appear to be consistent with the analysis. Unless I 'm misinterpreting, the results indicate that there was a difference between the two groups at that time point, not that each had a significant difference from the baseline. If this is the case, the conclusion should also to be adjusted accordingly. Response: We are sorry not to make it clear in the manuscript. While the reviewer’s interpretation was correct, we tried to explain how the significant interaction effect was driven. As shown in Table 2 from the submitted manuscript, while there was no significant difference between PA-P and PA in outcomes, the p-value (0.0105) obtained from ANOVA test tells us that an interaction term between group and time in regard to SBP was significant. To explain better and to identify where this was driven, we followed up with the post-hoc tests. In detail, this table shows that averaged SBP regardless the groups (PA or PA-P) was significantly reduced from Baseline to During-Time (p-value=0.0008) as well as to Post-Time (p-value=0.0267). On the other hand, the significance of the interaction,
