Except for age, univariate analyses also showed significant differences regarding DVT were current smoking (P = .001), alcohol consumption (P = .003), time from injury to operation (P = .019), albumin (P = .003), white blood cells (P = .016), lymphocyte (P = .030), red blood cells (P = .011), hemoglobin (P = .008), hematocrit (P = .042) and APTT (P = .017) among the 44 factors.
