Improving Nutritional Status Was Associated with Decreasing Disease Severity and Shortening of Negative Conversion Time of PCR Test in Non-ICU Patients with COVID-19.

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: Nutrition is an important prevention in old patients with COVID-19. However, in China, there are few studies on the correlation between nutrition and COVID-19. Methods: A total of 148 hospitalized COVID-19 (65.7 ± 16.0 [range: from 21 to 101] years old) patients were enrolled in this study. The information of demographic, biochemical results, vaccination doses, types of COVID-19, PCR test negative conversion time, and scores of Mini Nutritional Assessment Short Form (MNA-SF) for evaluating nutritional status were recorded. We first explored the relationships between MNA-SF performance and the severities of COVID-19 in the groups with non-vaccinated, vaccinated, and all the patients using multivariable ordinal logistic regression. Further, we explored the relationships between performance of MNA-SF and the time of negative conversion of PCR in the groups with non-vaccinated, vaccinated, and all the patients using COX proportional hazards survival regression. Results: Group of patients with malnutrition or at risk of malnutrition group was associated with older of the age, those who had not been vaccinated, in fewer people who were asymptomatic type and in more people who showed longer of the negative conversion time of PCR, lower of the BMI, and the lower of the hemoglobin level. Each additional increase of one point of MNA-SF was associated with a 17% decrease in the odds of a worse type of COVID-19 in all patients, and the significant result exists in non-vaccinated patients. One point increase of MNA-SF was associated with increased 11% of hazard ratios of turning negative of PCR and well-nourished group was associated with increased 46% of hazard ratio of turning negative of PCR. Conclusion: Higher nutrition is associated with less severity of COVID-19, especially in the non-vaccinated group. Higher nutrition is also associated with shorter time of turning negative of PCR in non-ICU COVID-19 patients.
