This correction updates the effect sizes for the association between age, sex, and respiration rate in the original study.
The original version of this Article contained an error in the Results section under the subheading 'Overview and demographics' , where the effect sizes for the associations between respiration rate and demographic factors (age and sex) were incorrectly reported.As a result, "Older participants had significantly slower RR, such that a 1 year increase in age corresponded to 1.35 breaths/ minute decrease in RR (p < 0.01, 95% CI=-1.73,-0.96).Participants with asthma were significantly younger than meditators (p=0.01,b=6.46, 95% CI= -11.31,-1.62) and non-meditators without asthma (p<0.01,b=-7.64,95% CI= -11.31,-3.96).There was no difference in pre-training, baseline RR in non-meditators with and without asthma (p=0.55,b=0.30, 95% CI=-0.68,1.27).There was no effect of sex on RR (p=0.94,b=0.00, 95% CI=-0.02,0.02)." now reads: "Older participants had significantly slower RR, such that a 1-year increase in age corresponded to .11breaths/ minute decrease in RR (p < 0.01, 95% CI=-.15,-0.08).Participants with asthma were significantly younger than meditators (p=0.01, b=6.46,) and non-meditators without asthma (p<0.01,b=-7.64,95% CI= -11.31,-3.96).There was no difference in pre-training, baseline RR in non-meditators with and without asthma (p=0.55, b=0.30, 1.27]).There was no effect of sex on RR (p=0.70,b=0.19, 1.16]).
