At this time, smoking was considered normal and harmless and a large percentage of the population smoked. Many people thought that pollution was the cause of lung cancer.

In the hierarchy of evidence, the higher up a methodology is ranked, the more robust and close to objective truth it is assumed to be. One of the most well known hierarchies of evidence, which is concerned with ranking the strength of evidence relating to the effectiveness of a treatment or intervention, is that developed by Sackett et al. (1996). This hierarchy of evidence goes in this order: 1 2 3 4 5 6 7 8 Systematic reviews and meta-analyses Randomised controlled trials Cohort studies, case controlled studies Surveys Case reports Qualitative studies Expert opinion Anecdotal opinion The implication of the hierarchy of evidence for the literature reviewer who has a research question concerned with treatment or intervention effectiveness is that greater weight should be given to relevant research identified that is higher up the hierarchy.
