From: Sleep disorders in rare genetic syndromes: a meta-analysis of prevalence and profile
Quality-effects pooled prevalence estimates for all sleep disorders, with 95% confidence intervals for each genetic syndrome (abbreviated). N refers to the number of papers used to generate the pooled prevalence estimates, QW the mean quality rating of these papers. Filled diamonds represent the estimates for sleep-related breathing difficulties, unfilled the estimates for insomnia. Filled circles represent the estimates for excessive daytime sleepiness, unfilled the estimates for sleep enuresis. Filled squares represent the estimates for sleep bruxism, unfilled the estimates for ‘general’ sleep difficulties
