摘要：

OBJECTIVE. To describe a method for deriving original data values from scanned images of graphs and scatterplots published in the medical literature. CONCLUSION. The procedure is simple, reproducible, and relatively error free (when performed carefully). This method is useful in converting published graphic material into numeric data for various uses when the original data are unavailable directly from the authors.
