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

objectivesFrailty is a syndrome characterized by increased vulnerability and reduced ability to maintain homeostasis after stressful events that results in an increased risk for poor outcomes. Frailty screening could potentially be valuable in cardiac surgery risk assessment. The purpose of this review is to evaluate the current literature linking multicomponent frailty assessment and invasive cardiac surgery outcomes.

methodsWe searched PubMed, EMBASE, and CINAHL; 1887 articles met the search criteria, and each was independently reviewed by 2 reviewers.

resultsThe 19 eligible studies assessed 52 291 subjects using 17 different frailty measurements. The most commonly used instruments were the Fried Frailty Phenotype and the Clinical Frailty Scale. Between 9% and 61% of participants were found to be frail in each study. All 19 studies included mortality as an outcome, 12 included surgical complications, 12 included hospital length of stay, 3 included quality of life, and 2 included functional status. Nine found statistically significant differences in survival between frail and nonfrail patients, 6 of 12 found that frail patients had a longer length of stay, 4 of 12 found that frail patients were more likely to experience major complications, and 2 of 2 found that frail patients were more likely to have a decrease in functional status.

conclusionAlthough some studies lacked power, the majority confirmed that frail patients are more likely to experience poor outcomes. Further research is needed to determine which frailty measure provides the best predictive validity and to identify interventions to mitigate the risks that major cardiac surgery poses to frail patients.
