1. Due to the limitations of FEV1 in the age
group of below 6 years, both FEV1 and PEFR were used in this study,
and their values were clinically interpreted and analyzed with GINA
criteria (as GINA criteria allows the use of either).
2. We regret a typographical error in mentioning
the duration of the study. The study was conducted from April 2014
to September 2014.
3. Indeed, the questionnaires were verbally
translated by the person administering the questionnaire.
Photographic representation of the responses provided as a feature
in the questionnaire, aided in helping the children understand the
questions and to optimally answer it. A written translated version
was not used because the study sample was heterogeneous with respect
to education level and the language spoken at home (varying from
Hindi, Bengali, Tamil, Telugu and Kannada). Hence, to maintain
uniformity, a standard English questionnaire was used, and was
verbally translated appropriately according to the participant’s
needs. Further, translated versions would itself need a validation
process before being used for the study.
4. One author was solely responsible for clinical
evaluation and the other author was involved in administering the
questionnaire.
