6. Figure E3
Funnel plot of pooled analysis. Case reports were combined in to 5 study groups according to the year of publication (1953–1974, 1975–1984, 1985–1994, 1995–2004, and 2005–2014); however, 1 study group (study period from 1995 to 2004) was not shown in the funnel plot because the mortality was zero, failing to make a comparison between the extent of torsion. OR, Odds ratio.
