1 · What the graph read from 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.

2 · The registry

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

backgroundSevere acute malnutrition (SAM) remains a growing public health concern in India, with increasing prevalence in recent national surveys. It is associated with impaired growth, neurodevelopmental deficits, and heightened infection risk. Inflammation and oxidative stress play central roles in its pathogenesis and mortality. Vitamin D (VD) has immunomodulatory and antioxidant effects, but its impact on inflammatory mediators and their regulators in SAM is poorly understood, with limited mechanistic evidence from human studies.

methodsPeripheral blood mononuclear cells (PBMC) were isolated from 10 participants suffering from uncomplicated SAM. The PBMCs were treated with VD for a period of 24 h following which the mRNA expression of inflammatory markers (TNFα & IFN γ), their modulators (SOCS1 & SOCS3) and PINK1 was measured by qPCR.

resultMean age of the participants was 30 ± 12 months. Following VD treatment, we noted a 2.4-fold decrease in mRNA expression of TNFα, 4.4-fold decrease in mRNA expression of IFN γ, 1.4-fold and 1.6-fold increase in mRNA expression of SOCS1 and SOCS3 compared to untreated ones (controls). No difference in mRNA expression of PINK1 was observed in the two group of cells.

conclusionVitamin D treatment is associated with a decreased expression of pro-inflammatory cytokines (TNF-α and IFN-γ) and a concomitant increase in expression of immunoregulatory genes SOCS1 and SOCS3 in PBMCs isolated from children suffering from uncomplicated SAM.
