HIV-1 subtype distribution and its demographic determinants in newly diagnosed patients in Europe suggest highly compartmentalized epidemics

Table 1 Percent subtypes for the complete set of patients and only for patients originating from SPREAD countries and 95% confidence intervals

	All patients	95% C.I.	Patients originating from SPREAD countries	95% C.I.	p-value
A1	6.92	[6.00-7.94]	5.24	[4.30-6.32]	p=0.012
B	66.12	[64.31-67.90]	79.48	[77.63-81.25]	p<2.2x10^-06
C	6.78	[5.86-7.79]	2.55	[1.90-3.34]	2.4x10^-11
D	0.81	[0.51-1.22]	0.15	[0.03-0.45]	N.S.
F	1.28	[0.89-1.78]	1.12	[0.70-1.69]	N.S.
G	3.81	[3.12-4.60]	3.31	[2.56-4.20]	N.S.
AE	3.95	[3.26-.76]	2.60	[1.94-3.40]	p=0.009
AG	4.73	[3.96-5.59]	1.73	[1.20-2.411]	p=2.1x10^-08
Others	0.59	[0.34-0.95]	0.20	[0.06-0.52]	N.S.
U/URFs	5.02	[4.23-5.91]	3.62	[2.83-4.54]	N.S.

P-values are for comparisons between the complete dataset and for the dataset including only patients originating from SPREAD countries.
AE – CRF01_AE.
AG – CRF02_AG.
Others – Samples classified as other subtypes or CRFs.
A1 – Sub-subtype A1.
B – Subtype B.
C – Subtype C.
D – Subtype D.
F – Subtype F.
G – Subtype G.
U/URFs – Samples classified as Untypable (U), partially Untypable or as Unique Recombinant Forms (URFs).
