摘要

Bland-Altman图在成对数据设置中很有用，例如测量方法比较研究。Bland-Altman图在y轴上表示差异、百分比差异或比率，在x轴上表示数据对的平均值，95%一致限表示差异、百分比差异或比率的中心95%范围。这个范围可以随平均值变化。我们引入了社区贡献的blandaltman命令，该命令在Stata中独一无二，可以1)创建除了差异和百分比差异之外还具有比率的Bland-Altman图，2)允许比率和百分比差异的一致性限制作为平均值的函数而变化，以及3)为图添加置信区间，预测区间和容忍区间。

blandaltman: A command to create variants of Bland–Altman plots

Bland–Altman plots can be useful in paired data settings such as measurement-method comparison studies. A Bland–Altman plot has differences, percentage differences, or ratios on the y axis and a mean of the data pairs on the x axis, with 95% limits of agreement indicating the central 95% range of differences, percentage differences, or ratios. This range can vary with the mean. We introduce the community-contributed blandaltman command, which uniquely in Stata can 1) create Bland–Altman plots featuring ratios in addition to differences and percentage differences, 2) allow the limits of agreement for ratios and percentage differences to vary as a function of the mean, and 3) add confidence intervals, prediction intervals, and tolerance intervals to the plots.
