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

objectivesThis review aimed to determine the pooled prevalence of preoperative anxiety and its associated factors among patients undergoing surgery in low/middle-income countries (LMICs).

methodsWe searched PubMed, SCOPUS, CINAHL, Embase and PsychINFO to identify peer-reviewed studies on the prevalence and factors associated with preoperative anxiety among patients undergoing surgery using predefined eligibility criteria. Studies were pooled to estimate the prevalence of preoperative anxiety using a random-effect meta-analysis model. Heterogeneity was assessed using I² statistics. Funnel plot asymmetry and Egger's regression tests were used to check for publication bias.

resultOur search identified 2110 studies, of which 27 studies from 12 countries with 5575 participants were included in the final meta-analysis. Of the total 27 studies, 11 used the State-Trait Anxiety Inventory to screen anxiety, followed by the Amsterdam Preoperative Anxiety and Information scale, used by four studies. The pooled prevalence of preoperative anxiety among patients undergoing surgery in LMICs was 55.7% (95% CI 48.60 to 62.93). Our subgroup analysis found that a higher pooled prevalence of preoperative anxiety was found among female surgical patients (59.36%, 95% CI 48.16 to 70.52, I

conclusionOur meta-analysis indicated that around one in two patients undergoing surgery in LMICs suffer from preoperative anxiety, which needs due attention. Routine screening of preoperative anxiety symptoms among patients scheduled for surgery is vital. PROSPERO REGISTRATION NUMBER: CRD42020161934.
