Table 2. Summary of studies investigating the association between carriage of the PlA2 polymorphism and ischaemic stroke that were unsuitable for inclusion in the statistical analysis.

Study Subject characteristics Comment
Addad et al, 2010 [57] Stable coronary artery disease (n = 188) Composite endpoint of major adverse cardiovascular events at 1 year was more frequent in subjects homozygous for PlA1 allele
Castro et al, 2004 [53] Homozygous for sickle cell anaemia (n = 97) No significant association between carriage of the PlA2 allele and risk of occlusive vascular events
Galasso et al, 2010 [49] Hypertensive patients with prior cerebrovascular event (74 cases, 100 controls) Carriage of the PlA2 allele associated with an increased risk stroke, both in terms of healthy controls and compared to risk of a transient ischaemic attack
Komarov et al, 2009 [54] Stable coronary artery disease (n = 287) Risk of composite cardiovascular end point was not elevated in patients carrying the PlA2 allele
Lalouschek et al, 2007 [64] Cerebrovascular event in patients <60 years old (450 cases, 817 controls) No significant association between carriage of the PlA2 allele and risk of stroke or transient ischaemic attack
Mustaffa et al, 2009 [50] Malay ischaemic stroke patients (91 cases, 104 controls) No difference in allele frequency between stroke patients and healthy blood donors
Pongracz et al, 2001 [52] Hungarian stroke patients (234 cases, 173 controls) Non-significant increase in carriage of the PlA2 allele among stroke patients >50 years old
Streifler et al, 2001 [51] Carotid artery stenosis (n = 153) Carriage of the PlA2 allele increased risk of stroke or transient ischaemic attack
Yeh et al, 2004 [55] Stroke patients <50 years old (n = 231) Carriage of the PlA2 allele was not associated with an increased risk of the composite cardiovascular end point at 1 year
Wei et al, 2009 [56] Ischaemic stroke patients (265 cases, 280 controls) Distribution of PlA2 allele was not different between ischaemic stroke group or control group
