Influencing factors and construction of a nomogram for post-stroke depression in patients with chronic stroke

Table 4 Assignment of variables

Factors	Variable	Assignment
Age (years)	X1	< 60 = 0, ≥ 60 = 1
Marital status	X2	Married = 0, divorced/widowed = 1
Education level	X3	Senior high school or above = 0, below senior high school = 1
Number of comorbid conditions	X4	0 = 0, 1 = 1, ≥ 2 = 2
Severity of neurological impairment	X5	Mild = 0, moderate = 1, severe = 2
Number of lesions	X6	Single = 0, multiple = 1
NLR	X7	Continuous variable
PLR	X8	Continuous variable
Post-stroke depression	Y	No = 0, yes = 1

NLR: Neutrophil-to-lymphocyte ratio; PLR: Platelet-to-lymphocyte ratio.
