Correlation of anti-heat shock protein 70 antibodies serum level with malnutrition-inflammation score in hemodialysis patients.
Article in International urology and nephrology, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIncreased levels of circulating heat shock protein 70 antibodies (anti-Hsp70) have been reported in hemodialysis (HD) patients. Since the anti-Hsp70 correlates with inflammation, it may associate with the malnutrition-inflammation score (MIS). The aim of this study was to determine whether the increased MIS score in HD patients are related to circulating levels of anti-Hsp70.
methodNinety HD patients with an arteriovenous fistula, aged 30-65 years, who underwent three hemodialysis sessions a week for at least the past 3 months at a hemodialysis center were enrolled in this cross-sectional study. Patients were divided based on MIS score to two groups, and the clinical and biochemical variables were compared between them. MIS cutoff score of ≥ 5 indicated the presence of malnutrition. The association between categorized MIS and anti-Hsp70 was examined using regression models adjusted for diabetes mellitus, hemodialysis vintage, BMI, albumin, hs-CRP, IL6 and endotoxin levels as confounding factors.
resultsThe univariate regression analysis revealed a significant association between MIS ≥ 5 and hemodialysis vintage, uric acid, hs-CRP, IL-6, endotoxin and serum anti-Hsp70 level. After adjusting the confounders, the association between MIS ≥ 5 and serum anti-Hsp70 level remained significant.
conclusionThese data support the role of serum anti-Hsp70 in the development of malnutrition in HD patients. However, further studies with body composition assessments and better generalizability are required to investigate the association between nutritional status and circulating anti-Hsp70 level in HD patients.
