Strength and limitations
We have reported very valuable and validated objective tool for
screening OD in patient with severe COVID-19. This is considered a
strength to our study. Moreover, using an objective test avoids the
response bias as patients can be influenced by the news that report
smell and taste dysfunction in COVID-19 and overreported these symptoms.
On the other hand, this study has some limitations where most of our
study population was having moderate to severe COVID 19 symptoms whom
required hospitalization; for that mild cases were missed. Finally,
duration of the symptoms and recovery rate were not assessed very well
in this study.
