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

backgroundWith a growing demand for endoscopic services, the role of anesthesiologists in endoscopy units must be reassessed. The aim of this study was to compare patient outcomes in non-anesthesiologist-administered propofol (NAAP) versus anesthesiologist-administered propofol (AAP) during routine endoscopy.

methodsWe systematically searched MEDLINE, CINAHL, Embase, Web of Science, CENTRAL and the grey literature for studies comparing NAAP and AAP. Primary outcomes included endoscopy- and sedation-related complications. Secondary outcomes included measures of endoscopy quality and of patient and endoscopist satisfaction. We reported treatment effects using random-effects models.

resultsOf 602 articles identified, 5 met the inclusion criteria. Most studies included only patients with an American Society of Anesthesiologists (ASA) classification of I or II. Non-anesthesiologist-administered propofol did not result in increased rates of airway intervention (odds ratio [OR] 1.07, 95% confidence interval [CI] 0.29 to 3.95; 3443 patients) or hypotension (OR 1.47, 95% CI 0.40 to 5.41; 17 978 patients) but did result in higher rates of bradycardia (OR 3.68, 95% CI 1.65 to 8.17; 17 978 patients). Nonanesthesiologists administered lower propofol dosages than anesthesiologists (mean difference -61.79, 95% CI -114.46 to -9.12; 3443 patients), and their patients more commonly experienced awareness with recall (OR 19.99, 95% CI 7.88 to 50.76; 2090 patients). However, NAAP neither compromised patient willingness to repeat the procedure (OR 0.42, 95% CI 0.10 to 1.83; 2367 patients) nor lengthened total procedure time (mean difference -0.08, 95% CI -3.51 to 3.34; 2367 patients).

conclusionEndoscopists may safely administer propofol without compromising procedural quality in patients classified as ASA I or II undergoing routine endoscopy. The results of this meta-analysis are limited by a lack of available high-quality studies. Further, large-scale studies are needed for definitive conclusions.
