How to fill out 428-2013 cox proportional hazard

How to fill out 428-2013 Cox Proportional Hazard:

1. Gather all necessary information: Before starting to fill out the form, make sure you have all the relevant data, such as the individual or event being analyzed, the time of occurrence, and any covariates or factors that may affect the hazard.
2. Start with the basic details: Begin filling out the form by providing general information about the study or analysis, such as the title, investigator's name, and date.
3. Define the baseline hazard function: In this section, you will need to specify the mathematical form of the baseline hazard function, which represents the hazard at time zero for individuals with all covariates set to zero.
4. Specify the time variable: Indicate the time variable used in the analysis, whether it is actual time, time since a specific event, or some other time scale. You may also need to specify the time unit used.
5. Enter the covariates: List all the covariates or risk factors that will be included in the analysis. Provide clear labels for each variable and specify the type (continuous, categorical).
6. Assign parameter estimates: For each covariate, estimate the corresponding regression coefficient, which quantifies the effect of the covariate on the hazard rate. Depending on the statistical software or program you are using, you may need to input the parameter estimates directly or specify the model equations.
7. Check for model assumptions: Ensure that the proportional hazards assumption holds, meaning that the hazard ratios for any two individuals are constant over time. Consider using graphical diagnostics or statistical tests to assess this assumption.
8. Interpret results: Once the form is filled out and the analysis is performed, interpret the results by examining the hazard ratios, confidence intervals, and p-values for each covariate. This will help identify the significance and magnitude of the effects.
9. Update the form as needed: If there are any changes or updates to the analysis or data, make sure to modify the form accordingly and repeat the steps to fill it out correctly.
