Table 6. Comparison of R545Q frequency in different populations

The asterisks denote a calculation based on adding 0.5 to each cell in cases with a zero cell frequency, otherwise the value is nonexistent. Lower and upper bounds refer to the individual study 95% confidence interval around the odds ratio for a fixed effects Mantel-Haenszel model. Information from Leung et al. [35] were omitted because it duplicated that contained in Fan et al. [15]. Data from Toda et al. [37] were omitted because it duplicated information contained in Tang et al. [20]. In the Europe category, only the data regarding Caucasians (Iowa and Australia) in Alward et al. [11] were enumerated, while the reported cases with pigmentary, developmental, and exfoliative data were omitted.
