Meta-analyses for all studies in children with sickle cell anemia that included FSIQ for those with and without SCIs. The meta-analyses include a total of nine published studies and the current analysis that compares the mean difference in FSIQ between those children with sickle cell anemia with and without an SCI. The x-axis reflects the mean FSIQ difference between those with and without an SCI. The horizontal lines represent the upper and lower boundaries of the 95% confidence interval. If the 95% confidence interval overlaps zero or crosses the zero threshold then no statistical differences were observed in that study. The black and gray diamonds represent the results of the fixed and random effect models. The edges of the diamonds represent the 95% confidence interval of the meta-analyses for the fixed and random effect models.
