In short
A facteur de confusion can distort the relationship being studied because it is connected with both the exposure being compared and the outcome, without being an intermediate effect of that exposure. In this hypothetical example, income may influence both access to a green neighbourhood and reported well-being. Tenir compte du revenu means considering that factor; it does not automatically remove every possible bias.
Yellow the idea to rememberBlue French to learn
In this hypothetical teaching example, a resident has read that people near parks report higher well-being. The researcher explains why that association alone does not show that the park caused it. The discussion separates the observed relationship, a possible third factor and a proposed follow-up study.

Observation, explanation and proposal
The observed association remains real within the supplied example. Introducing income does not prove that parks have no effect; it identifies a possible alternative influence. The proposed follow-up is also not a completed result. Keep pourrait, examiner and proposer where those words express the current evidence status.
