There were some different views about the best duration of condition to include in the study.
There were wide ranges of duration of condition, duration of present condition, and duration of treatment.
Age, gender, duration of condition and IES scores will be included as covariates in the analysis.
These were "treatment assignment", "gender", "age", "baseline SPADI", "sick leave at baseline", "baseline pain medication", "duration of condition" and "previous shoulder problems".
The characteristics of the participants in our trial were similar to those reported by others for age, height, sex, proportion with bilateral patellofemoral pain syndrome, duration of condition, severity of pain, anterior knee pain scale, and functional index questionnaire.
By their very nature, most studies are limited by such factors as subjects' ethnicity, geographical location, nationality and the nature of the medical data available (e.g., levels of severity, functionality, symptomatology, duration of condition).
This explanation cannot be tested in the current study due to the cross-sectional nature of the data, thus can only provide data on prevalence (which is influenced by both the duration of conditions and the incidence of new cases).
The cognitive processes involved in eliciting patients' preferences for health outcomes can be quite onerous and are affected by framing effects, contexts, anchoring points, duration of conditions, time preferences and attitudes towards risk [ 31, 32].
Examples of the dimensions used to classify diagnoses into the ADGs are severity of the condition, expected duration of the condition, and the need for specialty care involvement.
For YLD, the years of healthy life lost is obtained by multiplying the expected duration of the condition by a severity weight for the condition.
