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

purposeAlcohol consumption is associated with dose-dependent health loss secondary to long-term intake. In this scoping review, we sought to synthesize the literature on the association between the dose of preoperative alcohol consumption and postoperative outcomes. SOURCE: We included studies with adults undergoing cardiac and major noncardiac surgery reporting the dose of preoperative alcohol and postoperative outcomes. We searched MEDLINE, Embase®, and Cochrane Databases for Controlled Trials and Systematic Reviews. Outcomes were mortality, intensive care unit (ICU) admission, length of stay (LOS), delirium, surgical site infection (SSI), major cardiac and renal events, and postoperative pulmonary complications (PPCs). We assessed risk of bias (ROB) using the Newcastle-Ottawa Scale (cohort) and Joanna Briggs Institute tool (cross-sectional). We registered the protocol at PROSPERO (CRD42023474001). PRINCIPAL

findingsOf 9,591 references, we included 23 studies, and 7 exhibited high ROB. When consumed regularly, alcohol was associated with an increase in postoperative mortality (three of six studies), ICU admission (two of three studies), LOS (four of six studies), delirium (one of four studies), SSI (five of nine studies), and PPCs (one of three studies). No meaningful change in the results emerged when the high-ROB studies were removed. No consistent threshold of alcohol consumption was evident, though some studies implied an association with a dose of ≥ 2 drinks equivalents·day

conclusionsThe association between alcohol dose and postoperative complications is inconsistent across observational studies.
