Vitamin D modulates systemic inflammation in patients with severe COVID-19.
Article in Life sciences, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis 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
aimsThe ability of vitamin D (VitD) to modulate immune responses in the clinical setting of COVID-19 infection is not well investigated. This study aimed to evaluate the ability of VitD to attenuate inflammatory responses in patients with severe COVID-19. MATERIALS AND
methodsBlood samples and nasopharyngeal swabs were obtained from patients with severe COVID-19 who had been treated (20 patients), or not (25 patients), with VitD, during their stay in the intensive care unit. Western blotting was used to evaluate the expressions of STAT3, JNK and AKT signaling pathways and ELISA was used to measure levels of IL-6, IL-17, and IL-1β in blood of these patients. KEY
findingsReduced levels of STAT3, JNK and AKT pathways and lower levels of proinflammatory cytokines such as IL-6, IL-17, and IL-1β were observed in VitD treated patients (50,000 IU of cholecalciferol weekly for 3 weeks), and in vitro following treatment of poly I:C stimulated PBMCs with VitD (50 nM of calcitriol). Moreover, lower circulatory levels of these proinflammatory cytokines following treatment with VitD were associated with lower serum levels of COVID-19-related severity markers such as D-dimer and C-reactive proteins (P < 0.001) which in overall resulted in shorter length of ICU stay for VitD treated compared to untreated patients (18 days for VitD treated vs. 28 days for VitD untreated; P = 0.01). SIGNIFICANCE: This study reveals that VitD plays immunomodulatory role during COVID-19 infection, which further emphasizes the importance of maintaining a normal level of this vitamin for the prevention of hyperinflammatory conditions associated with COVID-19.
