Understanding secondary hypogammaglobulinemia and its implications for cancer prognosis in children: A retrospective cohort study
Observational study in Biomedica : revista del Instituto Nacional de Salud, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionImmunodeficiencies are disturbances in the immune system that can affect cell function, quantity, or both. They can be either primary, associated with genetic defects, or secondary, linked to external factors such as hemato-oncological conditions. Secondary immunodeficiencies can lead to the initiation, reactivation, or acceleration of latent, residual, or active infections, which are the leading cause of mortality.
objectiveTo elucidate the occurrence and clinical characteristics of hypogammaglobulinemia in pediatric oncology patients in a high-complexity hospital in Colombia between January 2020 and December 2022. MATERIALS AND
methodsWe conducted an observational study with patients under 18 years old with a cancer diagnosis, serum immunoglobulins measurements at the time of the diagnosis, and later follow-up during treatment.
resultsWe included 133 patients with a median age of eight years. Based on local guidelines of immunoglobulin levels for age, all patients had normal values at the time of cancer diagnosis. In the follow-up, the most significant reduction among all ages was for IgA and was related to infections and death.
conclusionsOur findings highlight the importance of measuring immunoglobulin levels at the time of the cancer diagnosis, as hypogammaglobulinemia may be linked to a poorer prognosis. Early detection could potentially improve patient outcomes.
