Contribution of Genetic and Clinical Risk Factors to Development of Candidemia in Patients Receiving Home Parenteral Nutrition.

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
backgroundPatients receiving home parenteral nutrition (HPN) have an increased risk for central line-associated bloodstream infections (CLABSIs), including candidemia. Recently, 7 single-nucleotide polymorphisms (SNPs) in TLR1, CD58, LCE4A-Clorf68, and TAGAP have been associated with the development of candidemia. Identification of host-genetic as well as clinical risk factors may help to identify patients who have an increased susceptibility to such infections. The aim of this study was to investigate the relevance of the reported SNPs in patients receiving HPN, and to explore clinical risk factors associated with candidemia.
methodsWe analyzed blood samples of adult patients who started HPN between 1976 and 2017 at our referral center for intestinal failure. Primary outcome was the association between TLR1, CD58, LCE4A-Clorf68, or TAGAP SNPs and candidemia. Secondary outcomes included the relation between severity of infection and these SNPs, and clinical risk factors for candidemia.
resultsOf 341 included patients, 42 (12%) experienced a candidemia (range 1-6). None of the 7 SNPs were associated with candidemia or the severity of infection. The rate of non-Candida-related CLABSIs was significantly associated with candidemia (rate ratio, 1.29; 95% CI, 1.14-1.46; P < 0.001).
conclusionsNone of 7 known SNPs in TLR1, CD58, LCE4A-Clorf68, or TAGAP were associated with candidemia or severity of infection in patients receiving HPN. The rate of non-Candida-related CLABSIs was significantly associated with the development of candidemia. The latter supports the key role of aseptic catheter handling with respect to Candida susceptibility in patients receiving HPN.
