Why did patients apply to this trial?

For the money. I'm healthy. Mid of February I got heavy flu, my employer took a covid test, she said the result not clear, she said I got covid and asked me to wear mask and rest. She gave some medicines, but I don't know what medicine they are. I had been coughing since that time till now. I went to Urgent Care, was given medicines but did not help.
