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

backgroundModerate acute malnutrition (MAM) affects millions of children, increasing their risk of dying from infections. Thymus atrophy may be a marker of malnutrition-associated immunodeficiency, but factors associated with thymus size in children with MAM are unknown, as is the effect of nutritional interventions on thymus size.

methodsThymus size was measured by ultrasound in 279 children in Burkina Faso with MAM, diagnosed by low mid-upper arm circumference (MUAC) and/or low weight-for-length z-score (WLZ), who received 12 weeks treatment with different food supplements as part of a randomized trial. Correlates of thymus size and of changes in thymus size after treatment, and after another 12 weeks of follow-up were identified.

resultsThymus size correlated positively with age, anthropometry and blood haemoglobin, and was smaller in children with malaria. Children with malnutrition diagnosed using MUAC had a smaller thymus than children diagnosed based on WLZ. Thymus size increased during and after treatment, similarly across the different food supplement groups.

conclusionsIn children with MAM, the thymus is smaller in children with anaemia or malaria, and grows with recovery. Assuming that thymus size reflects vulnerability, low MUAC seems to identify more vulnerable children than low WLZ in children with MAM. IMPACT: Thymus atrophy is known to be a marker of the immunodeficiency associated with malnutrition in children. In children with moderate malnutrition, we found the thymus to be smaller in children with anaemia or malaria. Assuming that thymus size reflects vulnerability, low MUAC seems to identify more vulnerable children than low weight for length. Thymus atrophy appears reversible with recovery from malnutrition, with similar growth seen in children randomized to treatment with different nutritional supplements.
