Age Period Cohort Characteristic (APCC) models provide a powerful method for testing theories that involve age, period, and cohort effects, but much of that power remains unrecognized. Studies that use this method almost always focus on a single explanatory cohort characteristic and control for only...

The slopes of the calibration curves were used to compare the predicted probability with the observed probability in the study cohort. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare the difference in the prediction accuracy between the model and the ...

Considering SM as a response variable (Table5), AGE represented a significant characteristic: an increasing age was correlated to a decreasing SM [β = − 0.232, Waldχ2(1) = 7.376, p = 0.007], controlling for the other predictors. Among the independent variables, WC, BA...
Mexico ranks fifth worldwide in the number of deaths due to COVID-19. Identifying risk markers through easily accessible clinical data could help in the initial triage of COVID-19 patients and anticipate a fatal outcome, especially in the most socioecono
Using several data sources from Chile, we study the impact of the size of the school choice set at the time of starting primary school. With that purpose,
Over a 5-day infection period, SARS-CoV-2 replication increased and then peaked at 72 h post infection (p.i.) (Extended Data Fig. 3a,b); therefore, all subsequent investigations were completed before this timepoint. The total number of viral reads increased with time but did not differ...
