Evaluation of meibomian glands in childhood malnutrition.
Article in Scientific reports, 2025. 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
Childhood malnutrition is a condition that affects a large population and can have significant implications for eye health. Our study aims to assess the impact of childhood malnutrition to the ocular surface by evaluating meibomian gland morphology and function. This study included 92 patients aged 6-18 years, with 52 diagnosed with malnutrition and 40 serving as healthy controls. Patients' nutritional status was determined based on body mass index (BMI) according to WHO criteria. Meibomian gland morphology and function were assessed using non-invasive imaging techniques and clinical evaluations along with the bloodwork results, including serum ferritin, hemoglobin, serum 25-hydroxyvitamin D, and vitamin B12 levels. Children with malnutrition exhibited significantly lower mean BMI, hemoglobin, serum 25-hydroxyvitamin D, serum ferritin levels and significantly worse meibomian gland loss (MGL) compared to healthy controls (p < 0.001 for all). However, differences in mean non-invasive tear break-up time (NI-BUT) and vitamin B12 levels were not statistically significant. Subgroup analysis based on malnutrition severity revealed no significant differences in MGL or NI-BUT levels. Negative correlations were observed between BMI and MGL, as well as between MGL and serum ferritin and 25-hydroxyvitamin D levels (p < 0.001 for all). This study provides novel insights into the ocular consequences of malnutrition in children, highlighting significant alterations in meibomian gland morphology and function associated with nutritional deficiencies. These findings may inform targeted interventions to reduce ocular morbidity and improve the overall health outcomes of malnourished children.
