Relationship of the Valsalva ratio to XXXX .

@entity1 @entity8 @entity6 @entity16 @entity3949 @entity305 @entity4148 @entity989
1. The Valsalva ratios (VR) of 48 @entity6 @entity1 and 48 normal individuals matched by age and sex were compared in order to examine the relationship between VR and the prevalence and severity of @entity989 , @entity16 and @entity8 , which are chronic complications of @entity6 . 2. @entity6 @entity1 without clinical evidence of @entity16 had the same VR (1.95 +/- 0.09) as the matched control group (1.95 +/- 0.14). @entity6 @entity1 exhibiting some evidence of @entity3949 showed VR values lower than their control groups (1.58 +/- 0.07 vs. 1.81 +/- 0.7), whereas @entity1 with symmetric sensitive @entity305 plus @entity4148 had the lowest VR scores (1.16 +/- 0.04 vs. 1.86 +/- 0.14). 3. An inverse relationship was shown between VR and the prevalence of @entity989 and @entity8 and the duration of @entity6 . Low VR values correlated well with the prevalence and severity of complications. 4. It is concluded that the Valsalva ratio is an effective indicator of @entity4148 .
