Neuroprotective Role of Oral Vitamin D Supplementation on Consciousness and Inflammatory Biomarkers in Determining Severity Outcome in Acute Traumatic Brain Injury Patients: A Double-Blind Randomized Clinical Trial.
Trial report in Clinical drug investigation, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 26 papers, 5 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
objectiveEarly management of traumatic brain injury (TBI) is essential. We aimed to evaluate the efficacy of vitamin D over early clinical outcome and serum cytokine levels in patients with moderate to severe brain injury.
methodsThirty-five patients with moderate to severe traumatic brain injury who were admitted to the ICU unit were recruited into the study. Subjects were randomly allocated to a treatment regimen comprising either a one-time oral dose of 120,000 IU (two tablets of 60,000 IU each) of vitamin D (n = 20) or 8 mg of saccharide (two tablets of 4 g each) as placebo (n = 15). The main parameters evaluated included duration of mechanical ventilation and ICU stay, Glasgow Coma Scale (GCS) and cytokine levels (interleukin (IL)-6, tumour necrosis factor (TNF)-α, interferon (IFN)-γ, IL-2).
resultsThe results indicated an improvement in the level of consciousness after 7 days in the vitamin D-treated group compared with placebo. An elevation in GCS score by 3.86 units in the vitamin D-treated group with a 0.19-unit descent in the control group was recorded. Duration of mechanical ventilation was reduced in the vitamin D-treated group compared with the control group (4.7 days vs. 8.2 days, p value 0.0001). A noticeable reduction was recorded in inflammatory biomarkers (cytokines) in the vitamin D-treated group (IL-6 p = 0.08, TNF-α p = 0.02, IL-2 p = 0.36) with notable elevation in IFN-γ (p = 0.65) compared to the control group.
conclusionIn the acute phase of moderate to severe traumatic brain injury, vitamin D supplementation plays a vital role and has a favourable effect on the consciousness level of patients. Clinical trial Registry (CTRI) No. CTRI/2019/05/019259.
