Expert writing Tips
Best practice
Use "which showed" to add additional, non-essential information about a preceding noun phrase. Ensure the clause is set off by commas.
Common error
Avoid using "that" in place of "which" when introducing a non-restrictive clause. "Which showed" requires a comma before it and provides extra, non-essential information, whereas "that showed" would introduce an essential clause without commas.
