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

objectivesDementia is a common mental disorder that affects the life quality in elders. Recently, emerging studies reported the negative impacts of dementia on prognosis after hip surgeries. However, the integrated and reliable role of dementia in hip surgery is not illustrated.

methodsWe searched the relevant literatures before June 2020 and extracted the data that met the inclusion criteria. The influence of dementia on postoperative walking ability, complications including infection, cardiovascular complications, hip dislocation, delirium, and respiratory complications, and survival rate at different periods were evaluated. Qualitative and quantitative analysis were conducted using Review Manager Version 5.3.

resultsThe meta-analysis enrolled a total of 30 studies with 1,037,049 patients. The pooled results revealed that there were significant negative impacts of dementia on the recovery of postoperative walking ability, postoperative infection, hip dislocation, delirium and respiratory complications and mortality at different periods.

conclusionsDementia is a crucial risk factor for the poor prognosis after hip fracture surgery. Therefore, when making clinical strategies for hip fracture patients with dementia, countermeasures for possible complications should be generated.
