Association between malnutrition risk and the prognosis of geriatric heart failure patients undergoing left ventricular assist device implantation.

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
backgroundEvidence regarding the association between malnutrition risk and the prognosis of geriatric heart failure (HF) patients undergoing left ventricular assist device (LVAD) implantation is lacking. Our study aims to investigate how malnutrition risk, assessed using the geriatric nutritional risk index (GNRI) values, relates to the outcomes of geriatric HF patients undergoing LVAD, using data from the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) registry.
methodsA retrospective analysis was conducted using data from INTERMACS registry. Patients aged 65 and above who received LVAD implantation between 2008 and 2017 were included. The GNRI was used to stratify patients into three groups: absence of risk (GNRI > 98), mild risk (GNRI 92-98), and moderate to severe risk (GNRI < 92). The primary outcome was long-term survival for up to four years following LVAD implantation.
resultsWe included 5429 patients aged 65 and above undergoing LVADs. The malnutrition risk was presented in 75.8% of the patients before implantation, decreasing to 32.4% at 3 months, and 59.5% at 24 months post-implantation. Moderate-to-severe malnutrition risk, both pre-implant and 6 months post-implant, was associated with an increased risk of death (pre-implant: hazard ratio (HR): 1.25 [95% CI: 1.12-1.40], p < 0.001; 6 months: HR: 2.36 [95% CI: 2.01-2.77], p < 0.001). Mortality decreased with increasing pre-implant GNRI up to approximately 100 and 6-month post-implant GNRI up to 104. Patients with malnutrition risk also had an increased risk of infection, poor quality of life (QoL), and reduced functional exercise capacity after the LVAD implantation.
conclusionsMalnutrition risk was highly prevalent in HF patients aged 65 and above undergoing LVADs implantation. The presence of malnutrition risk was associated with an increased risk of death, infection, poor quality of life, and reduced functional exercise capacity.
