How should gastric emptying data be summarized to allow comparisons between males or between groups of subjects within a study, and to facilitate comparisons of results from study to study. We review standardization issues for reporting gastric emptying data, discuss criteria for choosing a method of analysis, review methods which have been used to describe gastric emptying data, recommend trial of the power exponential curve, and illustrate its use in the analysis and interpretation of data from several studies involving different types of meals and different types of subjects. We show why nonlinear curves should be fit using nonlinear least squares.
胃排空数据应如何汇总，以便在研究中对男性之间或不同受试者组之间进行比较，并便于不同研究结果之间的比较。我们回顾了报告胃排空数据的标准化问题，讨论了选择分析方法的标准，回顾了用于描述胃排空数据的方法，推荐了幂指数曲线的试验，并举例说明了其在分析和解释来自几项涉及不同类型餐食和不同类型受试者的研究数据中的应用。我们展示了为何应使用非线性最小二乘法拟合非线性曲线。
