Table 5. Multivariable Cox (proportional hazard) regression analysis for triglyceride prognosticating stroke recurrence among first-ever stroke patients in Malaysia.

Models show estimated regression coefficient (b), standard error (SE), adjusted hazard ratios (Adj HR) with 95% confidence intervals (CI) and the corresponding p-values (n = 8,576). The outcome variable was a time-to-event variable; where the event was stroke recurrence (present or absent) and the time was the number of years to develop the event.

Variables	TG Model 1 (n = 5,074)		TG Model 2 (n = 5,074)		TG Model 3 (n = 5,074)
	b (SE)	Adj HR (95% CI)	b (SE)	Adj HR (95% CI)	b (SE)	Adj HR (95% CI)
Events	246		246		246
Abnormal triglyceride	0.31 (0.13)	1.36* (1.05, 1.77)	0.29 (0.13)	1.34* (1.03, 1.73)	0.25 (0.14)	1.28 (0.98, 1.66)
Dyslipidemia	0.61 (0.13)	1.84* (1.43, 2.37)	0.58 (0.13)	1.78* (1.39, 2.30)	0.58 (0.13)	1.78* (1.38, 2.30)
Hypertension			0.36 (0.15)	1.43* (1.06, 1.92)
Diabetes Mellitus					0.31 (0.13)	1.36* (1.05, 1.76)

Notes.

HR, Hazard Ratio = exp (β); 95% CI = exp(β-1.965*SE(β)), exp(β+1.965*SE(β)).

^*level of significance, p = 0.05

Interactions were unlikely.

Scaled and non-scaled Schoenfeld residuals test were applied to check the proportional hazard assumption of the model.
