The research, as mentioned above, examines the relationship between cancer and oxygen-based on topographic elevation; thus, it is observational in nature. The study is purposed to give the researcher a preliminary encounter to investigate phenomena that could not be tested logically under randomly regulated research. It has provided a proactive insight and developed both understandable and relatable hypotheses on the kind of evidence that should be included in future inquiries. This study is, therefore, critical because it provides a retrospective or pragmatic account where we can tangibly relate to what is happening in the real world; in this case, lung cancer. This study majorly focuses on investigating real-life variables such as oxygen and altitude, on establishing its correlation with the carcinogen.
The results of the findings give the impression that there exists a causal relationship between cancer and the response variables. However, it is established that the correlation with height is primarily restricted to lung cancer because it related to oxygen-independent environmental parameters. Analysis of the rampancy of cancer is a broad topic. For instance, the confounding potential of elevation expansively transcends through regions with varying heights. The confounding variable in this research is, therefore, elevation. Future research studies are instigated to base their analysis on adjusting elevation. Fortunately, there is accurate documentation of locality information that is easily accessible across the world.
Delegate your assignment to our experts and they will do the rest.
This kind of research employs a cross-sectional study method, which inclines to the uncontrolled confounding variable whenever there is an association to be expounded. There is, therefore, a need to devise an alternative method to minimize the risk of association with unmeasured confounding elements. In this study, confounding variables were controlled by focusing on an evenly elevated region but exhibiting varying dimensions of topographic elevation. Error-prone counties were then filtered before performing strategic stratification and groupings.
