From: CSF sTREM2 in delirium—relation to Alzheimer’s disease CSF biomarkers Aβ42, t-tau and p-tau
Time-dependent influence of waiting time for hip fracture surgery the CSF sTREM2. CSF was sampled immediately before surgery started. a Among patients without dementia, there was no correlation between the CSF sTREM2 level and waiting time for surgery from hospital admission (hours; waiting time for surgery). b In contrast, among dementia cases, the CSF sTREM2 level increased with time from hospital admission until surgery with a positive correlation coefficient (rs). The correlations are calculated for all patients with or without pre-existing dementia respectively, but patients with and without delirium are indicated by separate symbols. CSF: cerebrospinal fluid, sTREM2: soluble TREM2. rs: Spearman’s rho
