Coffee consumption in hemodialysis patients: how many?
Observational study in European journal of clinical nutrition, 2019. 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
BACKGROUND AND
aimsCoffee is one of the most widely consumed beverages worldwide. However, fluid intake restriction is an important and difficult challenge for hemodialysis (HD) patients. The aim of this study was to analyze the effect of coffee intake on hydration and nutritional parameters of HD patients.
methodsThis was an observational, cross-sectional, multicenter study where 373 HD patients from 8 dialysis centers in Portugal were enrolled. A face-to-face questionnaire was applied and patient's clinical and body composition parameters were analyzed. The sample was divided into 3 groups depending on coffee intake: group 1-don't drink coffee, group 2-drink 1-2 coffees/day and group 3-drink 3 or more coffees/day. Laboratory and body composition parameters were registered in the month prior to the questionnaire application. Body composition was assessed with the Body Composition Monitor (BCM; Fresenius Medical Care Deutschland GmbH, Germany).
resultsPatient's mean age was 67.2 ± 14.4 years and the mean HD vintage was 61.3 ± 56.2 months. Patients who reported drinking 3 or more coffees daily were younger, presented higher levels of potassium, phosphorus, diastolic BP, albumin and interdialytic weight gain (IDWG) and lower dialysis adequacy (Kt/V). Regarding body composition, patients in the group 3 showed higher body cell mass index (BCMI) and lean tissue index (LTI). On the other hand, the group 1 were the oldest, had a higher Kt/V, a lower diastolic blood pressure (BP) and potassium levels, whereas G2 presented a lower LTI, BCMI and IDWG.
conclusionsDrinking 3 or more coffees daily increases the risk of a higher diastolic BP, potassium and IDWG in HD patients.
