Does a standardized questionnaire for subjective estimates of exercise ability correspond with objective cardiopulmonary exercise testing in pediatric patients?
Does a standardized questionnaire for subjective estimates of exercise ability correspond with objective cardiopulmonary exercise testing in pediatric patients?

No takes yet. Share an insight, caveat, or question.
Subjective estimates should not guide individual pediatric management; leaves open whether routine objective testing improves risk stratification in larger cohorts.
Barber et al. (1991) studied this question.
