While there is an extensive literature on predictors of ECEC utilization in the United States and Europe, some of which specifically addresses children from disadvantaged families, most previous studies provide 'snapshots' within a given ECEC policy context, but few have documented the effects of ECEC policy changes.
For the first time the turning point in life quality will be presented and the contributions of an extensive set of predictors covering demographic, socio-economic, health and behavioural aspects will be assessed.
Using data from all the measures mentioned, an extensive set of predictors were derived taking into account the hierarchical nature of data distribution: neighbourhood level variables (level 2) and individual level variables (level 1)— table 1.
According to one of the hitherto most extensive reviews of predictors of long-term sick-listing for spinal pain, prior sick-listing for all diagnoses has been insufficiently studied [ 1].
It is, however, worth mentioning some factors that increase the likelihood of poor performance in a validation study: stepwise selection of variables from a large number of candidate variables with a small number of events, data-dependent cutpoint selection for continuous predictors, extensive missing data, a differently defined endpoint.
After adequate treatment (excision with free margins and radiotherapy), young age and incompletely excised extensive intraductal component are predictors for local recurrence, but many local recurrences can still not be predicted.
Existing literature converges on extensive differences between the predictors of subjective and objective QoL.
It is useful to refer to the extensive literature on the predictors of dropout and academic underperformance at medical school.
The extensive impact of those predictors (explaining 70% of the variance of antibiotic prescribing) demonstrates that efforts to reduce high antibiotic prescribing rates in RTI must focus on GPs' beliefs in pathogenesis and the misattributing of clinical signs and patient symptoms to bacterial infection.
Efforts to minimise adverse risk selection have also led the Netherlands to make extensive use of clinical predictors, grouping individuals into pharmaceutical and diagnostic cost groups to capture the costs associated with chronic illness at both primary and secondary care level [ 32].
