Firm conclusions however, cannot be drawn due to the limited number of reported studies, clinical heterogeneity of the interventions, variations in outcome measures and limitations in study designs.
Ramsey's Reset Test for the presence of omitted variables in the residuals was insignificant (F 3,236) = 0.18, p = 0.909), suggesting that the majority of between-intervention variation in cost per LY/QALY/DALY ratios is random.
1 Conducting the evaluation in areas where a single state lead implementing partner (SLP) was delivering the intervention helped minimize intervention variation due to implementation style of the SLP; it also minimized contextual effects that might arise from geographic and cultural differences across states in India.
However, due to the number of combinations of intervention types, variation in intervention details and possible emergent virus characteristics, exhaustive analysis has been impossible.
A structured approach builds upon objective measures and employs a hierarchy of interventions, reducing variation.
Whether these findings represent genuine age-related and/or sex-related differences in access to the ICU and related interventions, represent variation in patient preferences for provision of ICU support, represent other health policy or decision-making processes, or were unaccounted for confounding remains uncertain [ 33].
T3 translational research studies attempt to answer questions surrounding reliable implementation of interventions, decreasing variations in care, and spreading effective therapies.
The failure to blend relevant scientific knowledge and local knowledge and experience has been highlighted as a common limitation to matching tree-based interventions to variations in social-ecological context (Coe et al. 2014).
In the paper "Changes in free and open source software licenses: managerial interventions and variations on project attractiveness," [59] Carlos Denner Jr. analyzes the relationship between changes in licensing terms and projects' attractiveness.
It is possible that single center management can be confounded by unmeasured co-interventions and variation in practice.
