**3. Comprehending the framework for evidence**

Evidence of type 3 from an intervention context [38]. While many scholars have written around the context role it plays in providing information on the subject of evidence-based practice [32, 38, 51], there is not much consensus on its meaning. Context turn into more unknown as well as unpredictable, variable, and multifaceted as we move from scientific interventions toward population-level as well as policy interventions. Relevant definitions to the context highlight's evidence required toward modifying as well as implementing an information-based intervention in a specific population or context [38]. There are five overlapping domains in the conditions for Type 3 evidence (see **Table 2**). First, there are features of the intervention targeting demographic, for instance educational attainment as well as medical history. This is the reason why interpersonal variables provide the most important context. People with cancer history, for example, may be more susceptible toward getting cancer screening. Finally, organizational variables must be taken into account. For instance, if an organization succeeds in implementing an evidence - based program in which it is influenced through capacity (for example, agency leadership, a trained personnel) [51, 52]. Fourth, it is known that social norms and cultural traits are closely linked toward shaping several health behaviors. Ultimately, the greatest political as well as economic forces will influence the context. For example, large-scale measures of certain disease can impact a state's political will toward addressing the problems in a logical as well as methodical way. There is an urgent evidence need for contextual determinants as well as approaches

toward adapting programs as well as policies across contexts as well as demographic subgroups. Predominantly aimed at high-risk as well as understudied populations. Circumstantial COVID-19 pandemic questions remain being addressed in novel "realist review," which remains a systematic review procedure that not only examines if the recent intervention is working effectively but then again, in what manner interventions actually work in real-world contexts [53].
