THE SHORT VERSION
What’s worth knowing.
The key findings, what they mean, and the context that matters.
THE HEADLINE TAKEAWAY83%
Most symptomatic COVID-19 patients had ground-glass opacities on admission CT
Ground-glass opacities appeared on chest CT in 83% of symptomatic COVID-19 patients.
The source is a systematic review and meta-analysis of imaging manifestations at admission. This result concerns CT, not chest ultrasound or radiographs.

ABOUT THIS MONITOR
Understanding includes the limits.
This is an AI-assisted evidence summary, not a clinician endorsement. Read each original paper for its complete methods, population and limitations. Different studies can ask different questions and report different kinds of results.
Dates marked “added” describe when a finding entered this monitor, not when the study was published or clinically reviewed. Personal health and treatment decisions belong in a conversation with a qualified clinician.
