Shrinkage was required for all predictive models' coefficients ranging from -0.309 (prediction probability was inverse to observed proportion) to 0.823. Predictive models which include baseline symptoms as a feature produced the highest discrimination. Two models produced a predicted probability of 0 and 1 for all patients. Conclusions: Predictive models vary in performance and transferability illustrating the need for improvements in model development and reporting. Several models showed reasonable potential but efforts should be increased to improve performance. Baseline symptoms should always be considered as potential features for predictive models.]]> Wed 19 Jan 2022 15:16:35 AEDT ]]> Rectal and urinary dysfunction in the TROG 03.04 RADAR trial for locally advanced prostate cancer https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:21390 p< 0.001) in urinary dysfunction were measured using the EORTC PR25 instrument at 18 and 36 months. Conclusion: Adjuvant androgen suppression, bisphosphonates and increasing EBRT dose did not increase rectal or urinary dysfunction in this trial. However dose escalation using HDRB increased urinary dysfunction.]]> Sat 24 Mar 2018 08:05:03 AEDT ]]> Urinary symptoms following external beam radiotherapy of the prostate: Dose-symptom correlates with multiple-event and event-count models https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:22558 Sat 24 Mar 2018 07:14:46 AEDT ]]>
