Total number of individuals and TREM2 p.R47H carriers for each disease series and control group is shown in the table (left), with odds ratios and P-values represented in the forest plot (right). AD: Alzheimer’s disease, FTD: frontotemporal dementia, MCI: mild cognitive impairment, PSP-S: progressive supranuclear palsy syndrome, CBS: corticobasal syndrome, ALS: amyotrophic lateral sclerosis.
