Analyzing Factors Affecting Emergency Department Length of Stay-Using a Competing Risk-accelerated Failure Time Model.
TL;DR: Evaluating different effects of relevant factors affecting ED LOS among different patient disposition groups found common influential factors such as age, patient entity, triage acuity level, or arrival time may have varying effects on different disposition groups of patients.

Are psychological factors prognostic indicators of outcome in patients with sub-acute neck pain?
Jan J. M. Pool,Raymond W. J. G. Ostelo,Raymond W. J. G. Ostelo,Dirk L. Knol,Lex M. Bouter,Lex M. Bouter,Henrica C.W. de Vet +6 more
TL;DR: It is concluded that all psychological factors showed a considerable variation on the specific measurement and time point used, and only 'fear of movement' consistently impedes short term and long term recovery.

Influence of species richness and environmental context on early survival of replanted mangroves at Gazi bay, Kenya
TL;DR: There was no evidence that early survival of transplanted saplings is influenced by the species mix in which they are grown, or by their position in the plot, and the tolerance of individual species to salinity was the key to their survival at the high tidal site.

[Factors associated with breastfeeding duration in three cities in the region of Alto Jequitinhonha, Minas Gerais, Brazil].
TL;DR: Great education of fathers, use of pacifiers by children, and fathers not living with the children were factors associated with shorter duration of breastfeeding.
Estimación del tamaño de la muestra en la investigación clínica
TL;DR: The artículo incluye algoritmos para contrastes de hipótesis particulares como, por ejemplo, the comparación of proporciones inferiores al 5% o de curvas de supervivencia más exacto y pruebas estadísticas que permitan generalizar los resultados a la población completas.

Mineral Metabolism, Mortality, and Morbidity in Maintenance Hemodialysis
Geoffrey A. Block,Preston S. Klassen,J. Michael Lazarus,Norma J. Ofsthun,Edmund G. Lowrie,Glenn M. Chertow +5 more
TL;DR: Hyperphosphatemia and hyperparathyroidism were significantly associated with all-cause, cardiovascular, and fracture-related hospitalization, and the population attributable risk percentage for disorders of mineral metabolism was 17.5%, owing largely to the high prevalence of hyperph phosphatemia.

Survival and Prognostic Stratification of 670 Patients With Advanced Renal Cell Carcinoma
TL;DR: Five prognostic factors for predicting survival were identified and used to categorize patients with metastatic RCC into three risk groups, for which the median survival times were separated by 6 months or more.
