Age-period-cohort models in Stata In this article, I describe and illustrate Stata programs that facilitate i) the fitting of smooth age-period-cohort models to event data and ii) the plott... Peter,D.,Sasieni - 《Stata Journal》 被引量: 20发表: 2012年 A SAS program for evaluating ...

We develop an R package APCI (and Stata command apci) to implement the age-period-cohort-interaction (APC-I) model for estimating and testing age, period, and cohort patterns in various types of outcomes for pooled cross-sectional data and multi-cohort panel data. Package APC...
The analyses were undertaken on two outcomes: ADL and IADL using the same procedure. All analyses were weighted to reflect the French population using weights provided by INSEE, using the sampling weight procedure (pweight) from the survey [SVY] commands in Stata. All models included age terms...

In the youngest age cohort (70–74 years), 84.0% scored 4 points and 2.6% were unable to perform the subtest (0 points). For the older participants (85 + years), 20.2% scored 4 points and 31.0% were unable. In the oldest age cohort (95 + years), 3.6% scored 4 ...
In this framework, the importance of non-linear period and cohort effects is statistically tested on comparison with the simple trend model (age-drift model) as well as the two-factor (age – period and age – cohort) models. The final model was selected on the grounds of parsimony, using...
Data on patient volume were not available for cohort ophthalmologists, but UPCs have been shown to be an independent risk factor for risk management activity after controlling for clinical volume. Physician ages increased during the 14-year study period; however, given the mean 9.8-year follow-up...
We expressed the time trends in terms of age because this is biologically more meaningful than variations over the period of follow-up time. Age at baseline was included in the models to account for birth year effects. Although this variable was associated with the dropout patterns, there were...
The study team ran multivariable Cox proportional hazard models and flexible parametric survival models to estimate hazard ratios (HRs) and 95% CIs for AF according to preterm birth, SGA, and LGA. Sibling analyses were conducted to control for unmeasured familial factors. Results The cohort ...
