BD - blood donors from Lower Silesia region of Poland, EU - exposed, HIV-1-seronegative, HIV + - exposed to HIV and seropositive, 2DS4f - full-length KIR2DS4 gene, 2DS4del - KIR2DS4 with 22 base pair deletion, OR - odds ratio, based on the comparison of EU and HIV, CI 95 % - 95 % confidence interval, Bx - represents KIR genotypes AB and BB
