1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

aimsTo assess whether changes in social network drinking is a mechanism of behaviour change responsible for the benefits of attending Alcoholics Anonymous (AA) during a recovery attempt.

designAn observational longitudinal cohort study investigating mechanisms of behaviour change among adults with alcohol use disorder (AUD) reporting initiation of a substantial recovery attempt.

settingBoston, Massachusetts, United States, and Hamilton, Ontario, Canada.

participantsFrom a larger observational cohort, participants were individuals who reported a substantive increase in AA attendance (increase of ≥1 + meetings/week) from baseline to 6 weeks (n = 71) and a propensity score-matched control group of participants who did not increase AA attendance (n = 71). Propensity score matching used demographics and baseline drinking. MEASUREMENTS: Baseline assessment and a 6-week follow-up assessment, including outcome variables: diagnostic assessment of AUD, timeline followback interview [percent drinking days (%DD) and percent heavy drinking days (%HDD)]; and exposure variables: formal egocentric social network assessment collecting egocentric social network metrics and using up to 20 network alters.

findingsCompared with the control group, participants who increased AA participation statistically significantly reduced %DD [mean (M) = 5.67% (standard error of the mean, SEM = 1.81) vs 30.91% (3.59); F = 46.22, P < 0.001] and %HDD [5.21% (1.79) vs 23.32% (3.14); F = 28.34, P < 0.001] and exhibited statistically significantly improved social network indicators including reduced network drinking frequency [1.99 (0.08) vs 2.96 (0.09); F = 42.26, P < 0.001] and severity [1.68 (0.06) vs 2.34 (0.08); F = 40.51, P < 0.001]. Changes in social network drinking statistically significantly mediated the relationship between changes in AA attendance and reductions in %DD [b = -0.06 (0.02), P = 0.01] and %HDD [b = -0.05 (0.02), P = 0.04] at follow-up.

conclusionsReduced social network drinking appears to be one mechanism of behaviour change associated with the positive effects of Alcoholics Anonymous on drinking behavior during recovery.
