Not every sentence problem should be solved with a rewrite. Sometimes the strongest edit is a question.
This is especially true in medical and scientific editing, where precision matters and the editor may not be the content owner. A sentence may be awkward because the logic is incomplete. A claim may sound overstated because the evidence is being interpreted too broadly. A term may appear inconsistent because the author is distinguishing between concepts that are not yet clear to the reader. In those cases, silently rewriting the text can create risk. The editor may smooth the prose but unintentionally change the meaning. I see this frequently, to the point where the heavily edited content no longer aligns with the sources cited.
