What doctrine exactly is affected? I cant think of a single Bible where I couldnt prove the deity of Christ, trinity, doctrines of grace, salvation, or any other key doctrine from.
Its all in there. Even in the extremely "loosely" translated "the living bible". Its still all in there!
Compare KJV with other modern Bible versions.

1 Peter 2:2 - added grow up to salvation - works salvation
