Development and validation of a nomogram model for identifying post-stroke anxiety symptoms

Figure 3 Nomograph for identifying post-stroke anxiety symptoms. The nomogram incorporates five independent associated factors: Age, stroke type (ischemic vs hemorrhagic), central post-stroke pain (yes vs no), family history of stroke (yes vs no), and depression (Patient Health Questionnaire-9 ≥ 5). To utilize the nomogram, the points corresponding to each factor are summed to derive the total score, which is then mapped onto the bottom scale to estimate the probability of current anxiety symptoms (Generalized Anxiety Disorder-7 ≥ 5).
