BACKGROUND The strength of the association between undescended testis and testicular cancer varies considerably across studies. Here we report the effect of various classifications of self-reported history of undescended testis and different data sources on the estimates of the risk of testicular cancer from a case-control study. METHODS We performed a population-based case-control study incl...

The authors examined agreement between drug treatment data and a discharge diagnosis of diabetes, considered whether agreement was modified by demographic variables and measures of comorbidity, and evaluated construct validity through consideration of relations with subsequent mortality. The study sample comprised 81,700 residents of New Jersey aged 65-99 years who had prescription drug coverag...

AIM It has been recently shown that the original BODE index has a high degree of correlation with two modified BODE indexes using maximal oxygen uptake expressed either as mL/min/kg (mBODE) or as the percentage predicted (mBODE%). In this study we investigated the agreement between the two modified BODE indexes (mBODE and mBODE%) in patients with stable chronic obstructive pulmonary disease (CO...

OBJECTIVE Compare the scores resulting from the Comfort-B scale with the bispectral index in children in an intensive care unit. METHODS Eleven children between the ages of 1 month and 16 years requiring mechanical ventilation and sedation were simultaneously classified based on the bispectral index and the Comfort-B scale. Their behavior was recorded using digital photography, and the record...
