In addition to estimation of vehicle crash involvement risk, comparison of crash severity for RHD and LHD vehicles was undertaken as part of the first, i.e. a relative risk comparison of culpability for crashes and the third methodology, i.e. Poisson regression analysis.
The consent form was written in the local language stating the study's objectives, nature of participant's involvement, risk and benefits, and confidentiality of the data.
In cases of PTCLs, there have been few reports of the incidence of CNS involvement, risk factors or prognostic role on overall survival.
The initial radiotherapy tumour target volume included the prostate and base of seminal vesicles (SV) or complete SV depending on SV involvement risk.
Multivariate analysis using the Cox proportional hazards model disclosed two significant independent prognostic factors on disease-specific survival, the nodal involvement (risk ratio: 8.4; P < 0.0001) and the extent of lymph node dissection (risk ratio: 5.8; P < 0.005).
Medical records were revised; patient's age, tumor size, axillary lymph node involvement, risk group, pathological staging of tumor and lymph nodes and clinical evaluation for metastasis (pT pN cM) were determined as markers of aggressiveness.
