Abstract: INTRODUCCIÓN: Muchos artículos de revistas especializadas en psiquiatría usan la regresión logística para identificar el efecto de variables independientes sobre la probabilidad de ocurrencia de un evento. Evaluaciones de artículos publicados en otras especialidades médicas han mostrado que el reporte de la regresión logística es incompleto en muchos casos, lo cual implica dificultades para su interpretación. OBJETIVO: Evaluar la calidad, en cuanto al análisis de regresión logística y a al cumplimiento de crit… Show more

“…A backward stepwise logistic regression analysis using the likelihood ratio (LR) method and p<0.05 for entrance and p>0.10 for exclusion was performed to explore the potential association of antipsychotic polypharmacy with the five principal antipsychotics used most often, use of clozapine, LAI use, and other variables in the study. Hosmer and Lemesshow goodness of fit statistics and other literature recommendations were followed for logistic model construction [ 21 ]. Variables included in step 1 were: gender, age, marital status, schizophrenia subtype, SMD, psychiatric co-medication, psychiatric co-morbidity, consumption of substances, duration of disease; principal antipsychotic used (risperidone, olanzapine, paliperidone, zuclopenthixol, or quetiapine as dichotomous variables), clozapine use, and the use of LAI antipsychotics.…”

“…Subjects ranked with intermediate scores were excluded. Correlations between independent variables in the model scored low (237 to 256), a fact that allowed their incorporation into the model (Franco, Gaviria, Torres & Cotes, 2007). In order to include all impulsivity subtypes to the model, a backward procedure was applied and variables were progressively eliminated if necessary (if they did not make a significant contribution).…”

“…In order to include all impulsivity subtypes to the model, a backward procedure was applied and variables were progressively eliminated if necessary (if they did not make a significant contribution). The omnibus test was not significant, which indicates a good of fit and the possibility of using the output models (Franco et al, 2007). To estimate the effect size, Nagelkerke r 2 , a modified version of Cox and Snell r 2 , (Bewick, Cheek, & Ball, 2005) was applied.…”
