Abstract

Günümüzde, hastalıkların hemen hepsinin multifaktöriyel etiyolojilere sahip olduğu düşünülmektedir. Bir hastalığın ortaya çıkmasının birden fazla etkenin, farklı oranlarda ve farklı mekanizmalarla yaptığı etkiler neticesinde olması, aynı zamanda bir etken ile onun sonucu arasında diğer tüm etkilerden soyutlanmış bir ilişki olamayacağı anlamına da gelmektedir. Etken ile hastalık arasındaki ilişkiyi etkileyen ve nedenselliği çarpıtan üçüncül faktörler mutlaka olacaktır. Bu yüzden, epidemiyologlar ve bilimsel çalışmalar yürütecek olan diğer tüm araştırmacılar tarafından etki değiştirici, karıştırıcı, çarpıştırıcı ve mediyatör gibi kavramların bilinmesi ve çalışmaların tüm aşamalarında bu üçüncül faktörlerin mutlaka gözetilmesi gerekmektedir.

CAUSAL INFERENCE AND SOME IMPORTANT CONCEPTS: EFFECT MODIFIER, CONFOUNDER, COLLIDER, AND MEDIATOR

Abstract

In modern times, it is believed that most diseases have multifactorial etiologies. The emergence of a disease results from the combined effects of multiple factors operating at different rates and through different mechanisms. This also implies that there cannot be a relationship between a cause and its outcome that is isolated from all other influences. There will always be third factors that influence and distort the relationship between a cause and a disease. Therefore, it is crucial for epidemiologists and all other researchers conducting scientific studies to be aware of concepts such as effect modifier, confounder, collider, and mediator and to consider these third factors throughout all stages of their research.

Keywords

Causality, effect modifier, confounding variable, confounder, collider, mediator
