Abstract

Cochrane systematic review updating evidence on brief interventions in primary care. 68 RCTs showed moderate-certainty evidence that brief interventions reduce alcohol consumption by an average of 20 grams of alcohol per week compared to control at one year follow-up in adults.

    At a population level, most alcohol-related harm is not due to drinkers with severe alcohol dependence but attributable to a much larger group of excessive (hazardous and harmful) drinkers whose consumption exceeds recommended drinking levels.

    The true impact of alcohol on the health of individuals and the wider community is difficult to estimate because of the many effects resulting from alcohol use, including increased levels of violence, accidents and suicide.

      The Alcohol section (page not available) reports a substantial health burden from alcohol use, and the Limitations section says estimates of alcohol consumption rely on limited data and carry significant uncertainty. These passages support the broad point that alcohol’s impact is difficult to estimate, but they do not establish the claim’s stated reason—that difficulty arises from its many effects—or clearly link alcohol use to the listed increases in violence, accidents, and suicide.

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Fleming 2004 follow-up denominators exceed its stated group sizes

    Minor

    The intervention group is given as 81 participants, but the loss-to-follow-up calculation uses 92 as its denominator. The corresponding control figures are 70 and 75.

  • Córdoba 1998 has two different practice counts

    Minor

    The overview says Córdoba 1998 randomised 33 practices, while its study-characteristics entry says it randomised 74.

  • A trial is both included in and excluded from the primary meta-analysis

    Minor

    Crawford 2010, Díez 2002 and Drummond 2009 are named as primary-meta-analysis trials, but the review also lists them among studies that could not enter its meta-analyses.

  • Trial described as women-only had predominantly male participants

    Minor

    The primary-analysis description calls McDevitt-Murphy 2014 a women-only trial, whereas its study characteristics report 91.2% male participants.

  • Discussion gives an inconsistent overall baseline consumption

    Minor

    The discussion describes mean baseline consumption as about 310 g/week, but the results and clinical-importance sections give the overall mean as 244 g/week. The figure near 310 g/week is identified elsewhere as applying to older studies.

  • Crawford 2010 is incorrectly described as men-only

    Minor

    The primary-analysis description places Crawford 2010 among men-only trials, but its study characteristics report that 51% of participants were male.

  • Patient-satisfaction study is identified by conflicting years

    Minor

    Two sections identify different Drummond trials as one of the two studies reporting patient satisfaction: 2009 in one section and 2014 in the other.

  • D'Amico follow-up fractions use completer counts as losses

    Minor

    The stated loss of 22 out of 38 is 57.9%, not 42%. The adjacent control-group figure has the same problem: 20 out of 26 is 76.9%, not 23%.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
