Taken together, the large size of the investigation, the consistency of the observations in 4 independent caseecontrol series and the low P values distinguish our study from previous studies investigating the influence of different other polymorphisms on the development of SARS, and strengthen the association between the CCL2 G-2518A and MBL codon 54 variant (A/B) and susceptibility to SARS-CoV infection. ./cache/cord-282433-p6jl9gxf.txt ./txt/cord-282433-p6jl9gxf.txt
