Correction to: Treatment of periodontal intrabony defects using autologous periodontal ligament stem cells: a randomized clinical trial
Stem Cell Research & Therapy volume 9, Article number: 260 (2018)
The original article  contains a major error carried across the captions of Tables 1, 2, and 3. In each table caption, the data were expressed as “mean ± standard deviation (SD)”; unfortunately, the authors had mistakenly expressed the data as “mean ± standard error (SE)” instead. As such, all mentions of “mean ± standard error” in those table captions should of course state “mean ± standard deviation”. The authors are deeply sorry for these errors.
