Outcomes and complications of nonagenarians undergoing cardiac surgery: a scoping review protocol.
Article in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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
introductionContinually rising life expectancy and a shift towards an ageing population are resulting in an increasing population of nonagenarians. By 2030, the global population of nonagenarians is expected to exceed 30 million. The incidence of symptomatic cardiac disease is reported to occur in 25% of those aged over 75 years. Therefore, the number of nonagenarians undergoing cardiac surgery is also expected to increase. A linear relationship between advanced age and surgical risk has previously been demonstrated; however, it is not yet known whether this knowledge extends to the perioperative course and mortality of nonagenarians undergoing cardiac surgery. This scoping review aims to review the literature, assess whether a deficiency exists in the published literature and potentially identify knowledge gaps to guide future efforts to improve the understanding of nonagenarians undergoing cardiac surgery. METHODS AND ANALYSIS: Following the relevant aspects of the Preferred Reporting Items for Systematic Review and Meta-Analysis Extension for Scoping Review guidelines, electronic databases of MEDLINE, EMBASE and the Cochrane Library will be systematically searched, with additional reference tracking of eligible studies. Studies reporting the outcomes of nonagenarians undergoing open cardiac surgery or minimally invasive cardiac surgery requiring cardiopulmonary bypass will be included. Screening and data extraction will be performed by two reviewers independently. The data will be analysed and summarised descriptively with a narrative approach. Qualitative data that capture quality-of-life outcomes will be subjected to thematic analysis where feasible. Additionally, reporting results will highlight similarities and differences in nonagenarian selection for surgery. ETHICS AND DISSEMINATION: Ethics approval was not required. The findings will be disseminated through professional networks, conference presentations and publications in scientific journals.
