The importance of nutritional status on clinical outcomes among both ICU and Non-ICU patients with COVID-19.
Observational study in Clinical nutrition ESPEN, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 4 of them syntheses that pooled 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.
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
aimsThe current Covid-19 outbreak becomes a tremendous public health concern worldwide. Since a little information is available on nutritional status and its devastating effects on covid-19 complications in Iran, in the present study, we aimed to evaluate nutritional status of covid-19 population and its related factors.
methodsWe performed this observational study by recruiting 400 hospitalized covid-19 subjects. Thereafter, the needed clinical and para clinical data were collected and their nutritional status was then assessed using NRS-2002.
resultsApproximately 36% of the total sample size and 100% of the ICU- admitted cases were at the severe risk of malnutrition. The patients with NRS≥ 5 were significantly older (p < 0.0001). Non-survivals obtained higher scores in terms of both severity of disease (86%) and impaired nutritional status (67%), and this relationship was found to be statistically significant (p < 0.0001). In regard to the obtained prognostic inflammatory scores, 86% of the non-survivals obtained significantly highest scores for GPS (P = 0.015).
conclusionNutritional status has a considerable effect on clinical outcomes of covid-19 patients, which should be evaluated. Thereafter, rapid subsequent nutritional interventions must be implemented in this regard. As well, special attention must be paid to both elderly population and individuals with underlying diseases.
