The donor area was distributed into 14 zones, with the minimum depth required for at least three atraumatic extractions of the grafts. When the extraction was not successful, 0.5\u2009mm was added until reaching three follicular units, determining the DC area.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Approximately 2000 extractions were performed on each patient to determine DC. For some areas, greater depth (2.54\u2009\u00b1\u20090.10\u2009mm) was necessary. Fifty\u2010eight percent of follicular units were extracted with 2.0\u2009mm\u2009DC, and 3.8% required 3.5\u2009mm\u2009DC. Thus, according to Boaventura's new classification for DC, grade I\u2009\u2265\u20092.00\u2009mm, grade II from 2.1 to 3\u2009mm, and grade III\u2009&gt;\u20093.0\u2009mm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>There is variability in the DC of follicular units within the different areas of the safe donor zone.
