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

backgroundAlzheimer's disease (AD) is among the leading cause of nursing home admission (NHA). Identifying potentially modifiable factors associated with the risk of NHA is crucial to reduce this risk in individuals with AD.

objectiveWe aimed to assess the relationship between comorbidity burden, as measured by the Charlson comorbidity index, the multimorbidity-weighted index and the health related quality of life comorbidity index, and NHA in patients with AD.

methodsWe conducted an observational longitudinal study including patients from the MEMORA real-life cohort. Patients had to be aged 60 years or older, with a diagnosis of AD. The association between comorbidity indices and occurrence of NHA was assessed using Cox proportional-hazards models and competing-risks regressions considering mortality as a competing event. All analyses were adjusted for age, sex, educational level, stage of AD and the presence of neuropsychiatric symptoms.

resultsOverall, 488 AD patients were included (68.2% with dementia). There were 125 (26%) NHA that occurred during the follow-up, with a median time of 25 months until NHA. Higher level of comorbidity burden as measured by the three comorbidity indices was associated with higher risk of NHA compared to lower level of comorbidity burden. Similar findings were found after considering mortality as a competing event, with a HR of 2.41(95%CI:1.36-4.28, p = 0.003) for MWI, an HR of 1.96(95%CI:1.22-3.17, p = 0.006), and an HR of 1.68(95%CI:1.04-2.71, p = 0.034).

conclusionThe implementation of appropriate interventions that aim to improve the management of the comorbidity burden could help to reduce the risk of NHA in individuals with AD.
