如何将gtsummary表表头的CI替换为葡语IC？两种方法尝试无效

以下是针对你的问题的具体解决方案：

1. 确认主题设置的优先级 #

确保theme_gtsummary_language()在所有表格创建代码之前执行，它是全局主题配置，必须先加载才能影响后续生成的表格：

# 先设置葡萄牙语主题
theme_gtsummary_language("pt", big.mark = ".", decimal.mark = ",")

# 再执行表格生成代码
dados1 |> 
  tbl_summary(...) |> 
  add_ci(...)

2. 针对单独CI列的表头修改 #

如果add_ci()生成了独立的CI列，但表头未自动替换为IC，可直接用modify_header()指定列名修改（分组场景下列名为ci_1、ci_2，对应你的by = insulina分组）：

modify_header(
  label ~ "**Variável**",
  ci_1 ~ "**IC**",  # 第一组的CI列表头
  ci_2 ~ "**IC**"   # 第二组的CI列表头
)

3. 针对合并到统计量中的CI（你的代码场景） #

你的代码通过add_ci(pattern = "{stat} [{ci}]")将CI数值合并到了统计量单元格中，此时单元格内只有数值，无“CI”文本。若要添加葡萄牙语的“IC”标识，直接修改pattern参数即可：

add_ci(pattern = "{stat} [IC {ci}]")

如果想更灵活地复用主题配置，也可以引用主题内置的语言变量：

add_ci(pattern = "{stat} [{theme_gtsummary_get()$lang$ci} {ci}]")

完整修改后的代码 #

theme_gtsummary_language("pt", big.mark = ".", decimal.mark = ",")
