Prognostic Significance of Immune Abnormalities in Children with Severe Sepsis.
Article in Indian journal of pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesTo evaluate the immunoglobulin levels and lymphocyte subsets in children with severe sepsis at admission to the pediatric intensive care unit (PICU) and correlate them to mortality.
methodsA prospective study was conducted on 52 children with severe sepsis/septic shock. Serum immunoglobulins and lymphocyte subsets were measured at diagnosis in all patients and after 3 mo in survivors. Regression analysis was used to identify factors associated with mortality.
resultsThe median (interquartile range, IQR) age was 5 (3-7.5) y, with 62% boys. The median (IQR) time to hospital admission was 7 (4-10) d. Common diagnoses were acute meningoencephalitis, pneumonia, and tropical fever. At admission, the most common immune abnormality was low Natural killer (NK)-cell count (92%), followed by low T-cells (40%) and B-cells (36%). Among immunoglobulins, elevated IgM (27%) was most frequent, while low IgG (17%) and IgA (13%) were seen in a smaller subset. In this cohort, 19 (37%) children died due to severe sepsis. Low IgG was an independent predictor of mortality (OR: 2.77; 95% CI: 1.22-6.28; p = 0.014), irrespective of other immune abnormalities, time to presentation, gender, age at presentation, and illness severity score. At 3-mo follow-up, immune parameters normalized in most survivors, though some showed persistent lymphopenia (mostly low NK-cells), though all were clinically well.
conclusionsLow NK-cells, elevated IgM, and low T-/B-cells were common at admission in children with severe sepsis. Low IgG was an independent predictor of mortality. Most immune abnormalities were reversible at 3-mo follow-up.
