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: Dementia is widely recognized as a factor that influences the outcomes of total knee arthroplasty (TKA). However, recent studies have not fully elucidated the effects of dementia on perioperative medical and surgical complications, as well as in-hospital resource utilization. The objective of this study is to evaluate the specific impact of dementia on perioperative outcomes in elderly patients undergoing TKA. Methods: Data on elderly patients undergoing TKA were extracted from the National Inpatient Sample database (2010-2019). Patients were categorized into a dementia group and a non-dementia group. Propensity score matching (PSM) was employed to control for differences in demographics, hospital characteristics, and comorbidities. Multivariate logistic regressions were conducted to evaluate perioperative outcomes. Results: From 2010 to 2019, a group of 344,200 patients undergoing TKA was identified, among whom 6761 individuals (2.0%) were diagnosed with dementia. Following PSM, dementia remained an independent predictor for several perioperative outcomes, including urinary tract infection (aOR = 2.001, 95%CI = 1.561-2.564, Conclusion: Dementia is independently associated with an increased risk of perioperative complications after TKA, underscoring the importance of tailored perioperative care for elderly patients with dementia.
