Effectiveness of screening and ultra-brief intervention for hazardous drinking in primary care: pragmatic cluster randomised controlled trial

Context Hazardous drinking affects about one in five primary‑care
patients. The EASY study compared a ≤1‑minute ultra‑brief intervention
(Ultra‑BI) with simplified assessment only (SAO) across 40 primary care
clinics in Japan.  Objective To provide open access to datasets
and SAS / R scripts needed to reproduce the published analyses and support
future studies including independent participant data meta-analyses.

recruited at clinics that restricted screening to patients suspected of
hazardous drinking Six analysis scripts and one CONSORT-diagram script Key
variables  participant id, clinic id, allocation group, AUDIT-C score
(0–12), total alcohol consumption (grams per 4 weeks), WHO drinking risk
level (DRL), readiness-to-change score, sex, five-year age band,
comorbidities, smoking status, visit type, and participant reported
recognition of receiving advice. Reuse potential  The dataset and scripts
enables full replication of the published analyses, and pooled effect
estimates in individual participant data meta-analysis. Ethical
consideration Public data sharing was conducted under IRB-approved written
informed consent and public disclosure, with participants given the
opportunity to decline data sharing. All data were de-identified prior to
release, including the removal of direct identifiers and the aggregation
or masking of potentially re-identifiable information.
