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

backgroundFrailty has been suggested as a possible risk factor for postoperative delirium (POD). However, results of previous studies were not consistent. We performed a meta-analysis of cohort study to evaluate the above association.

methodsRelevant studies were obtained via systematic search of PubMed, Embase, SCOPUS, and Web of Science databases. Only studies with multivariate analysis were included. A random-effect model incorporating the potential heterogeneity was used to combine the results.

resultsFifteen cohort studies including 3250 adult patients who underwent surgery were included, and the prevalence of frailty was 27.1% (880/3250) before surgeries. Overall, POD occurred in 513 patients (15.8%). Pooled results showed that frailty was associated with a higher risk of POD (adjusted odds ratio [OR]: 3.23, 95% confidence interval [CI]: 2.56-4.07, P < 0.001) without significant heterogeneity (P for Cochrane's Q test = 0.25, I

conclusionsFrailty may be associated with a higher risk of POD in adult population.
