... bladder cancer were stratified by the modified self-administrable comorbidity index and Charlson score, respectively. Multivariate logit models (for 90-day mortality) and proportional-hazards models (for overall and non-bladder cancer mortality) were used for statistical workup. Results: Considering 90...

... years (median 5.7 years). Proportional hazard models for competing risk were used to identify predictors of non-bladder cancer (competing) mortality. The following parameters were included into multivariate analyses: age, American Society of Anesthesiologists physical status classification, Charlson...

... was compared using Mann-Whitney U test, chi-square test, or Fisher exact test. Cox proportional hazard models were used for the analysis of competing risks and logit models were used for the prediction of the receipt of adjuvant cisplatin-based chemotherapy. Results: Female patients were older, healthier, less...

...M. Takashi; T. Murase; S. Mizuno; N. Hamajima; Y. Ohno To clarify the relative importance of factors affecting the survival of patients with bladder cancer, a multivariate analysis by Cox’s proportional hazards model was performed on 264 patients initially treated from 1973 to 1984 at Nagoya...
