The incidence of deep vein thrombosis (DVT), diagnosed by ascending phlebography, was calculated in two Swedish districts. The average incidence per thousand population and year was 0.85 in males and 0.68 in females. Before the age of 50 the incidence was very low and almost the same in both sexes. After age 50 the incidence in men markedly increased with age. A similar increase was found in women, but not before age 60. DVT occurring after age 50 was significantly more common in men than in women. The study strongly suggests male sex as a risk factor for DVT.
通过上行静脉造影诊断的深静脉血栓形成（DVT）发病率在瑞典的两个地区进行了计算。每千人口每年的平均发病率男性为0.85，女性为0.68。50岁之前发病率非常低，且男女发病率几乎相同。50岁之后男性发病率随年龄显著增加。女性也有类似的增加，但在60岁之前没有。50岁之后发生的DVT在男性中比在女性中明显更常见。该研究强烈表明男性是DVT的一个风险因素。
