Best practice
Reserve this phrase for formal reports, scientific papers or legal documents where precision regarding causality is necessary
Common error
Avoid using "alterations affected" if your intention is to describe changes that were created. "Affected" means 'influenced' or 'impacted', whereas "effected" means 'accomplished' or 'made to happen'. Using the wrong term changes the meaning from 'changes that were made' to 'changes that were influenced by something else'.

Ludwig AI confirms its status as a formal expression, particularly prevalent in scientific and technical literature. While it may be less common than simpler alternatives like "changes made", it offers a level of precision regarding causation that is often required in professional writing.
