Table 1: _Cont._Figure 3 illustrates the number of articles analyzed yearly, where the most common where ten in 2017; six in 2002, 2015, and 2018; and five in 2005, 2009, and 2016. Figure 4 illustrates the leading countries where the first author's institution publishing the CTS articles is located (only those countries with at least two publications are shown; for a complete list, see the Supplementary Material). The United States presented 15 publications, followed by Turkey with 9, and the United Kingdom with 8; however, countries such as Brazil, Iran, and Italy have also deepened their study of CTS matters. The departments with a high commitment regarding CTS are associated with neurology, orthopedic surgery, neurological sciences, physical medicine and rehabilitation, orthopedic and traumatology, among others. For a complete list of departments, please see the complementary material.
