Table 3. Results of univariable logistic regression models predicting joint PCR and ECG status at follow-up.

	OR(95%CI)	p-value
Age (years)	0.98 (0.96 to 1.01)	0.156
Sex (male)	0.82 (0.50 to 1.35)	0.437
Hypertension	1.10 (0.66 to 1.84)	0.710
Diabetes	1.63 (0.78 to 3.36)	0.189
Smoking status (current or previous)	0.58 (0.35 to 0.95)	0.033
Donation S/CO <4	6.89 (2.31 to 24.2)	0.001
Follow-up S/CO <4	4.85 (2.25 to 11.1)	<0.001
Decline >1 S/CO	5.40 (2.13 to 15.5)	0.001

Odds ratios (OR) greater than 1 indicate variables associated with joint negative PCR and normal ECG status at follow-up
