Note. Cho et al. (2013) [45], Grignani et al. (2015) [47], Lee et al. (2009) [6], and Zhao et al. (2013) [44] did not report the grade of stomatitis; Richly et al. (2006) [52], Shacham-Shmueli et al. (2012) [54], and Williamson et al. (2010) [57] reported the incidence rates limited to grade 3 and grade 4 treatment-related toxicities; for this reason, data about cases of stomatitis and stomatitis grades 1 and 2 are lower than real.
