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

background and purposeThe outbreak of the COVID-19 pandemic has resulted in an overall decline in fractures. However, the amount of hip fractures has remained relatively stable throughout the period. The objective of this study is to investigate the impact of perioperative COVID-19 infections on mortality among hip fracture patients.

methodsA meta-analysis was performed by collecting current data available through a systematic literature search in the PubMed database. The search was performed Oct 18 2020.

resultsThe meta-analysis was conducted on a trial population consisting of 1.272 hip fracture patients with a pooled prevalence of COVID-19 of 18%. Mortality among hip fracture patients without a perioperative COVID-19 infection was 7.49%. Mortality among hip fracture patients infected with COVID-19 perioperatively was associated with an odds ratio of 6.70 [(95% CI 4.64-9.68), p < 0.00001, I

conclusionPerioperative infections with COVID-19 in hip fracture patients are correlated with a significantly increased mortality. The meta-analysis showed a pooled odds ratio of 6.70 [(95% CI 4.64-9.68), p < 0.00001, I
