The effect of XXXX on relative mortality in type 1 ( @entity2690 -dependent) @entity6 mellitus.

@entity1 @entity644 @entity6 @entity2690 @entity204 @entity65
We followed 1,134 @entity1 with Type 1 ( @entity2690 -dependent) @entity6 , diagnosed between 1933 and 1952, until 1982 or @entity204 or until their emigration. Their age at onset of @entity6 was under 31 years. Information concerning the development of persistent @entity644 was sought in every case. In 104 cases, the data were either questionable or the @entity1 could not be traced. Twenty-nine @entity1 developed non-diabetic @entity644 . Among the remaining 1,001 @entity1 , 406 developed persistent @entity644 (350 died) and 595 did not (166 died). The incidence of persistent @entity644 was highest among @entity1 ; it decreased with increasing year of @entity6 onset from 1933 to 1952, and decreased with increasing age at onset. The relative mortality was extremely high among @entity1 with persistent @entity644 , increasing to a maximum of about 100 at age 35 years. @entity1 not developing @entity644 had a relatively constant low relative mortality of about 2. The decreasing incidence of persistent @entity644 and the decreasing mortality with increasing calendar year of @entity6 onset resulted in a 50% increase in life-expectancy among @entity1 diagnosed in 1950 compared with @entity1 diagnosed in 1935. In @entity1 who developed persistent @entity644 , relative mortality was higher in @entity1 than @entity1 at all ages. In @entity1 who did not develop @entity644 , relative mortality was similar in @entity1 and @entity1 after the age of 35. Uraemia was the main cause of @entity204 in @entity1 with persistent @entity644 , although @entity65 were more frequent than in @entity1 without @entity644 . Thus, @entity644 is associated not only with @entity204 from uraemia but also from @entity65 .(ABSTRACT TRUNCATED AT 250 WORDS)
