However, there is a perception among some that environmental and occupational epidemiology is falling short of satisfying the needs of risk assessors. The specific reasons for this are not clearly understood. To help identify the points of dissatisfaction and possible areas for mutual learning, we conducted a survey of risk assessors, seeking their opinions of epidemiology research. We present a few quantitative measures and a thematic analysis of responses to open-ended questions. Survey results suggest that some risk assessors (with some adamant exceptions) believe that epidemiology has great potential to contribute to risk assessment but can be deficient in many ways. For example, respondents identified the lack of full disclosure of methods, deficiencies in exposure assessment, the absence of comprehensive uncertainty analyses, and the failure to investigate or explore thresholds of effects as some of the common shortcomings. These could be straightforward to address. Respondents also brought up a wide collection of more complicated and subtle concerns that could lead to further improvement of useful results. We identify areas where mutually-educating interdisciplinary dialogue seems particularly promising. Epidemiology research is expensive, and risk management decisions even more so; therefore, it is desirable for the risk assessment and epidemiologic communities to work toward making epidemiologic research more useful for informing decisions.</div></div>","PeriodicalId":36311,"journal":{"name":"Global Epidemiology","volume":"8 ","pages":"Article 100167"},"PeriodicalIF":0.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424362","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The subject has received considerable attention from epidemiologists and the field boasts a remarkable arsenal for addressing the issue.

In this commentary, I examine whether analysis of the properties of change-in-estimate method for identification of confounding, exemplified by two highly cited papers, has been appropriately cited in published reports and whether it was utilized to improve epidemiologic practice. I conclude that the myth that a change-in-estimate criterion of 10 % is legitimate for identifying confounding persists in epidemiological practice, despite having been discredited by several independent research groups decades ago. Speculations on possible solutions to this problem are offered, but my work's main contribution is identification of a problem of how methodological advances in epidemiology may be misapplied. There currently do not exist any universal criteria for identification of confounding! “Citation without representation” or biased presentation of conclusions of methodological research may be pervasive.</div></div>","PeriodicalId":36311,"journal":{"name":"Global Epidemiology","volume":"8 ","pages":"Article 100166"},"PeriodicalIF":0.0,"publicationDate":"2024-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424326","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
