Unfortunately I’m in the same boat. What appears especially telling is:

> tVNS applied for 30 min daily over 7 consecutive days increased VO2peak by 1.04 mL/kg/min (*95% CI: .34–1.73*; P = .005), compared with no change after sham stimulation (−0.54 mL/kg/min; *95% CI: −1.52 to .45*)

(emphasis mine) The 95% CIs for the case and control groups overlap. Seems borderline irresponsible to have a the abstract reporting a significant result.
