In the January-March2022 issue ofthe Indian Journal Respiratory Care, Walankar and Tare established gender-specific prediction equations for a 2-min walk test (2MWT) in healthy Indian subjects. Walankar and Tare stated a few study limitations. We believe that the following methodological limitation is contributory. Among many determinants, ethnicity and socioeconomic standard control physical activity and fitness.[2,3] Ethnic and socioeconomic disparities are noticeable phenomena in India. Regrettably, Walankar and Tare did not consider the ethnic and socioeconomic backgrounds in the studied population. Hence, such methodological limitation might further preclude the applicability of the constructed prediction equations for 2MWT in clinical setups and research.
