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

purposeTo systematically identify predictors of gastrointestinal (GI) bleeding in adult intensive care unit (ICU) patients.

methodsWe conducted a systematic review and meta-analysis of cohort studies including trial cohorts. We searched MEDLINE, EMBASE, and trial registries up to March 2019. Eligible studies assessed potential predictors of clinically important GI bleeding (CIB; primary outcome) or overt GI bleeding (secondary outcome), had > 20 events, and presented adjusted effect estimates. Two reviewers assessed study eligibility, extracted data, and assessed risk of bias and certainty of evidence using GRADE. We meta-analysed adjusted effect estimates if data from ≥ 2 studies were available.

resultsWe included 8 studies (116,497 patients). 4 studies (including 74,456 patients) assessed potential predictors of CIB, and we meta-analysed 12 potential predictors from these. Acute kidney injury (relative effect [RE] 2.38, 95% confidence interval [CI] 1.07-5.28, moderate certainty) and male gender (RE 1.24, 95% CI 1.03-1.50, low certainty) were associated with increased incidence of CIB. After excluding high risk of bias studies, coagulopathy (RE 4.76, 95% CI 2.62-8.63, moderate certainty), shock (RE 2.60, 95% CI 1.25-5.42, low certainty), and chronic liver disease (RE 7.64, 95% CI 3.32-17.58, moderate certainty) were associated with increased incidence of CIB. The effect of mechanical ventilation on CIB was unclear (RE 1.93, 0.57-6.50, very low certainty).

conclusionsWe identified predictors of CIB and overt GI bleeding in adult ICU patients. These findings may be used to identify ICU patients at higher risk of GI bleeding who are most likely to benefit from stress ulcer prophylaxis.
