s allele risk_factor_for depression

Carriers of the low-transcribing S allele exhibited more depression ... after stressful life events than L individuals.

we investigated the associations between stressful life events ... and the number of S alleles ... on depression as the response variable.

risk of depression increasing with the number of S alleles in the presence of stressful life events

Logistic regression models were used to test the associations between the explanatory (number of S alleles ...) and response variables (depression).
