From: CSF sTREM2 in delirium—relation to Alzheimer’s disease CSF biomarkers Aβ42, t-tau and p-tau

Fig. 4

Relation between the level of CSF biomarkers sTREM2 and Aβ42 in hip fracture patients. a Among patients without pre-existing dementia, there was no correlation between sTREM2 and Aβ42 in CSF, but (b) a positive relation in patients with dementia as indicated by a significant and positive correlation (rs). The correlations are calculated for all patients with or without dementia respectively, but patients with and without delirium are indicated by separate symbols. The dotted lines show the pathological biomarker cut-off level (530 pg/ml). To present Figs. 4 and 5 in the same manner, the x-axes in Fig. 4 are reversed because a low level indicates Aβ pathology. CSF: cerebrospinal fluid, Aβ42: amyloid beta 1–42, sTREM2: soluble TREM2. rs: Spearman’s rho
