PMC4083033 勘误的唯一改动类型

来源：PMC4083033（Europe PMC fullTextXML）

原句：
"In detail, female skin was thicker than those of males, which is consistent to many other previous studies [3,15,20]."

更正句：
"In detail, men have thicker skin than do women, which is consistent to many other previous studies [3,15,20]."

结论

这条勘误不是插入型，而是整体替换 / rewrite 型：
- 语义主语从 ''female skin'' 改为 ''men''
- 谓语与比较结构整体改写（''was thicker than those of males'' → ''have thicker skin than do women''）
- 句尾参考文献保持不变

最小差分（粗粒度）

Token 级 diff 显示为：
- replace: ''female'' → ''men have thicker''
- delete: ''was thicker''
- replace: ''those of males'' → ''do women''

因此，虽然实现上包含删除与替换混合操作，但从勘误类型上应判定为''替换 / rewrite''，不是纯插入。
