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
aimsNovel Coronavirus (COVID-19) first appeared in China in late 2019 which was rapidly spread worldwide. As the COVID-19 pandemic continues to spread, it is crucial to determine the prognostic factors contributing to the development of severe disease and higher mortality. Herein we aimed to evaluate the correlation between the severity and prognosis of patients with COVID 19 with serum 25(OH)D levels.
methodThis descriptive retrospective study was performed from March to April 2020 at a referral center for patients with COVID-19, Tehran, Iran. The data collection was performed by a checklist consisting of the demographic features and laboratory assessments consisted of serum 25(OH)D were evaluated and recorded. And investigate the relationship between serum 25(OH)D and clinical outcomes of patients.
result205 patients with a mean age of 59.71 years were enrolled. Our findings did not reveal a significant difference in mean levels of vitamin between improved (34.09) and deceased patients (34.54). However, in patients with severe disease, there was a considerable difference in levels of vitamin D in improved and deceased patients (P.value: 0.021). According to our results, the mortality rate was slightly higher in men (odds ratio:2.2). Furthermore, the mean age (64.20 vs. 58.51) and the presence of at least two comorbidities (odds ratio: 2.40) were significantly higher in deceased patients.
conclusionIn this study, we did not reveal a statistical difference in mean levels of vitamin D and the outcome of patients with COVID-19. We concluded that in patients with severe disease, vitamin D deficiency could affect the course of the disease and mortality, especially in comorbidity and older people.
