Once we have completed the current programme, using it as a baseline, I'd like to see a "lighter touch", shorter and more proportionate inspection model – one that retains an all-important scrutiny of casework and the experiences of children, identifying a small number of key areas to act upon.
Independent predictors of survival using the Cox proportionate hazards model are presented in Table 2 >.
The relationship of immunohistochemical covariates (expressed as the ratio of staining intensity between colon and liver), clinical and pathological features to survival after hepatic resection was investigated by a Cox proportionate hazard model.
We believe privacy concerns can be attenuated by human rights protections and robust safeguards built within a principled proportionate governance model (Sethi and Laurie 2013) and a code of conduct that recommends sharing sensitive data within strict limits that respect both laws and ethical guidelines (i.e. sharing data only with "prescribed entities" or within data "safe havens").
Univariate Cox proportionate hazards modelling was performed using an unadjusted model for each covariate, and we then constructed a multivariate model using a forward elimination method and entry criteria of p≤0.05.
Effect modification by individual risk factors was examined by fitting separate proportionate hazard models for each group (e.g., sex) in each city, controlling for covariates and combining across cities as in the main analysis.
HRs for suicide attempt, suicide and all-cause mortality in 2006 2010 were calculated by Cox proportionate hazard regression models, adjusted for sex, country of birth, parental education and parental and previous own suicidal behaviour.
The relative contribution of each predictor in the final regression models was determined by its proportionate contribution to the regression model R using the Pratt index, which is the product of the estimated standardized regression coefficient and the simple correlation between that predictor and the outcome variable (Chao et al. 2008; Pratt 1987).
The dynamics of a model with proportionate harvesting has been studied by Mena-Lorca et al. [21].
Furthermore, we set steady-state form for population model and fitness proportionate selection policy for parent selection model.
