Weather as physiologically equivalent was not associated with XXXX onsets in Vienna, 2004-2010.

@entity64 rates were found to have seasonal variations. However, previous studies using air temperature, humidity, or air pressure separately were not adequate, and the study catchment was not clearly drawn. Therefore, here we proposed to use a thermal index called physiologically equivalent temperature (PET) that incorporates air temperature, humidity, wind speed, cloud cover, air pressure and radiation flux from a biometeorological approach to estimate the effect of weather as physiologically equivalent on @entity385 onsets in an Austrian population. Eight thousand four hundred @entity64 events in Vienna registered within the Austrian @entity64 Unit Register from January 1, 2004 to December 31, 2010 were included and were correlated with the weather data, obtained from the Central Institute for Meteorology and Geodynamics in the same area and study time period and calculated as PET (  C). Statistical analysis involved Poisson regression modeling. The median age was 74  years, and @entity1 made up 49  % of the entire population. Eighty percent had @entity101 while 25.4  % were current smokers. Of note, 26.5  % had @entity6 , 28.9  % had pre- @entity64 , and 11.5  % had pre- @entity583 . We have observed that onsets were higher on the weekdays than on the weekend. However, we did not find any significant association between PETs and @entity385 onsets by subtypes in Vienna. We did not observe any significant associations between PETs and @entity385 onsets by subtypes in Vienna. Hospital admission peaks on the weekdays might be due to hospital administration reasons.
