CSF complement protein boxplots for classification groups combining cognitive and pathological status. Boxplots illustrating the log-transformed and z-scaled for all complement protein data in cerebrospinal fluid. A CSF complement proteins score in A + /A − subgroups. B CSF complement proteins score in A − T − /A + T − /A + T + subgroups. C–H CSF complement protein score in the diagnostic groups stratified by A + /A − status. A − , Aβ42 negative; A + , Aβ42 positive; C1q, complement C1q subcomponent subunit B; C2, complement C2; C5, complement C5; C6, complement C6; C8B, complement component C8 beta chain; CFB, complement factor B; CSF, cerebrospinal fluid; T − , p-tau negative; T + , p-tau positive. *p < 0.05, **p < 0.01, and ***p < 0.001
