> We then estimate a series of multilevel linear models using quality of life as dependent variable with individuals (level 1) nested in countries (level 2) (Rabe-Hesketh & Skrondal, 2005).
Our data have inherent multilevel, dependency structure, as quality of care data collected at the individual patient level are clustered within health centres which in turn are clustered within jurisdictions.
To measure long-term quality-of-life (QOL) improvement following contemporary multilevel upper airway reconstruction surgery, compared with continuous positive airway pressure (CPAP) therapy.
To investigate how a multilevel item response theory (IRT) model for longitudinal dependent data could provide average and individual quality-of-life outcomes of low-vision rehabilitation.
Future research could also include analyses that simultaneously examine the association between the provider outcomes and facility characteristics, such differences in number of available providers in the facility and quality of infrastructure, using multilevel modelling techniques.
Thirdly, to assess the questionnaire's ability to measure differences in quality of care between hospitals, multilevel analyses were performed using the MLwiN software package [ 39].
Similarly, although our multilevel models did consider country variations of quality of life, we may nevertheless ask if strengths of associations between social circumstances, labour market disadvantages and quality of life differ between countries.
Owing to the higher amount and the better quality of power transferred, three-phase multilevel inverters have strengthened their presence in low-power photovoltaic (PV) applications.
To account for the multilevel structure of quality assessments nested within videotaped consultations and individual observers, multilevel regression analyses were applied.
A multilevel random-effects model demonstrated a significant relationship between quality of chronic care delivery and the wellbeing of patients.
