Prognosis and persistence of smell and taste dysfunction in patients with covid-19: meta-analysis with parametric cure modelling of recovery curves

Dear Editor
Hello I was wondering why they only had people 18 years or older in the research. I am only asking because I have a 11 year old daughter that had covid 19 in September 2021 which she had serve headache with lots of pain at the beginning and then she lost her taste than her smell from covid. It been almost a year and can not find no clinical trials or research on children.

Thank you for your time,
Tammy Smith
