What is the meaning of 'Certified' and 'Certified-Withdrawn' in the status column?

When i try to search employers sponsoring H1 B visas whihc are cap exempt, the status column for many companies shows ‘Certified’ & ‘Certified-Withdrawn’? What does it exactly mean? How can i directly search companies who sponser cap exempt H1 B VISA for healthcare in USA?

Certified’ & ‘Certified-Withdrawn’ are related to LCAs, not H1Bs
