Sir,

This is in reference to the article "Hearing evaluation in mobile phone users at a tertiary care hospital" published in Indian J Otol 2014;20:24-8. [1] The authors have done an excellent job in highlighting an issue with huge public health impact, given the ever increasing number of mobile users in this country. The authors deserve congratulation for this.

However, I have a few concerns. The authors state that the aim of the study was to assess the status of hearing in a chronic mobile phone user and the impact of long-term exposure to mobile phones. However, nowhere in this study did I find a mention on the duration of time for which the study was conducted or the duration of time for which participants were recruited in this study. Furthermore, nowhere in the article did I find a mention as to how participants were identified as long-term users. In other words, what was the case definition of long-term use? Was it a single day long time use or a persistent long time use? This is important because a single time long time use may not yield us the stated aim of impact assessment.

This takes me to more important issue in this study. The authors state that 100 subjects were selected randomly from students of a medical college and were asked to answer a short preliminary questionnaire, which was used to segregate them into study groups. Now once students are segregated on the basis of a certain variable (as done by the authors), study losses the benefit of randomness. It becomes a case-control study and like all case-control studies is subjected to bias if case and controls are not adequately matched for. The authors could have highlighted on this aspect in the material and methods section of this article.
