Criteria for discontinuing or modifying allocated interventions
ADVERSE EVENTS, EVENT, ADVERSE EVENT, COVID-19 INFECTION
We will seek consent from participants and conduct the trial after signing the informed consent form, and the individual wishes of the participants will be considered. If the participants do not consent and refuse to participate in the experiment, we will respect their views, postpone or alter the intervention, and report the exact reasons. The trial will be stopped if a participant is exposed to harmful conditions in the event of a possible or impossible adverse event or emergency (COVID-19 infection, acute exacerbation of illness, life-threatening situation). We will take proactive steps to provide appropriate treatment and care to patients who have adverse events during the trial.
