Comparative evaluation of the reliability and validity of three data extraction programs: UnGraph, GraphClick, and DigitizeIt

作者：

Highlights：

• Reliability and validity of three data extraction programs were investigated.

• Three coders extracted data from 60 graphs of SSER using the three programs.

• Results showed high degrees of reliability and validity of the programs.

• The three programs can be used to extract data from SSER study graphs.

• Extracted data can be used in meta-analyses of SSER with high level of confidence.
