This study focused on the understudied group of smokers who commit to a smoking research study and then subsequently drop out before completing even one session of treatment (pre-inclusion attrition). This is an important group typically not examined in their own right, leaving little knowledge about the characteristics that differentiate them from those who complete treatment. As an initial in...

The purpose of this study was to elucidate the relationship between large tubules and dentin caries by using human deciduous incisors that showed various levels of attrition but no macroscopical lesions resulting from caries. The teeth were cut longitudinally in the mesio-distal direction and the exposed surfaces observed with a high-resolution field emission scanning electron microscope. The i...

The aim of this descriptive observational study was to assess the possible risk factors contributing towards dental attrition. The sample consisted of 200 patients, 100 in case group and 100 in control group all falling in the age group of 15-60 years. The patients were evaluated for the dental and occlusal variables, craniofacial and morphological variables, soft tissue and functional variable...

BACKGROUND Mortality and morbidity from HIV have dramatically decreased in both high- and low-income countries. However, some patients may not benefit from combination antiretroviral therapy (cART) because of inadequate access to HIV care, including attrition after care initiation. METHODOLOGY/PRINCIPAL FINDINGS The study population included all HIV-infected patients receiving cART through th...

OBJECTIVES To examine age differences in mortality and programme attrition amongst paediatric patients treated in four African HIV programmes. METHODS Longitudinal analysis of data from patients enrolled in HIV care. Two-year mortality and programme attrition rates per 1000 person-years stratified by age group (<2, 2-4 and 5-15 years) were calculated. Associations between outcomes and age and...

Animals in a poor biological state face reduced life expectancy, and as a consequence should make decisions that prioritize immediate survival and reproduction over long-term benefits. We tested the prediction that if, as has been suggested, developmental telomere attrition is a biomarker of state and future life expectancy, then individuals who have undergone greater developmental telomere att...

BACKGROUND Attrition is a serious problem in intervention studies. The current study analyzed the attrition rate during follow-up in a randomized controlled pediatric weight management program (EPOC study) within a tertiary care setting. METHODS Five hundred twenty-three parents and their 7-13-year-old children with obesity participated in the randomized controlled intervention trial. Follow-...

Previous research has shown L1 attrition to be restricted to structures at the interfaces between syntax and pragmatics, but not to occur with syntactic properties that do not involve such interfaces ('Interface Hypothesis', Sorace and Filiaci in Anaphora resolution in near-native speakers of Italian. Second Lang Res 22: 339-368, 2006). The present study tested possible L1 attrition effects on ...

19 ABSTRACT {Continue on reverse if necessary and identify by block number) Because pregnancy accounts for a large proportion of the attrition among enlisted Marine Corps women, an investigation was conducted of the effects of traditional family/career orientation, feelings of isolation, and feelings of dissatisfaction with the Marine Corps on incidence of pregnancy and pregnancy attrition amon...
