In order to evaluate the impact that code review coverage and participation have on software quality, the authors extract code review data from the Gerrit review databases of the studied systems, and link the review data to the integrated patches recorded in the corresponding VCSs.

The data extraction approach is broken down into three steps: (1) extract review data from the Gerrit review database, (2) extract Gerrit change IDs from the VCS commits, and (3) calculate version control metrics.
