Associations of prior wasting malnutrition with later indicators of glucose tolerance across 4 countries in Africa and Asia: The Severe Acute Malnutrition - the Role of the Pancreas (SAMPA) study.

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
backgroundPrenatal or infant wasting malnutrition followed by later overweight is associated with increased risk of chronic diseases, including type 2 diabetes.
objectivesIn a pooled analysis of 6 longitudinal cohorts, we investigated associations between prior malnutrition (PM) early in life or in adulthood and subsequent glycemic status.
methodsWe identified cohorts in Tanzania, Zambia, India, and the Philippines in whom low birth weight or wasting malnutrition in childhood or as adults following human immunodeficiency virus or tuberculosis infection had been measured. Anthropometry, body composition, and glycemic status, determined by hemoglobin A1c (HbA1c), and glucose at 120 min in an oral glucose tolerance test (glucose120), were assessed 3-38 y after PM and in non-PM (NPM) controls. HbA1c and glucose120 were compared between PM and NPM participants by linear regression, controlling for age, sex, and socioeconomic status and, in pooled analyses, for cohort also.
resultsIn the full cohort of 2251 participants, there was no overall association between PM and diabetes risk. Child participants aged ∼12 y who were hospitalized with PM when <2 y had higher glucose120 compared to NPM (difference 0.50 mmol/L; 95% CI: 0.10, 0.91 mmol/L). In pooled analyses across adult cohorts controlling for cohort, age, sex, and socioeconomic status, PM participants, compared to NPM, may have higher glucose120 (difference 0.33 mmol/L; 95% CI: -0.27, 0.92 mmol/L) if still underweight, and higher HbA1c (difference 0.41%; 95% CI: -0.07%, 0.89%) and glucose120 (difference 0.70 mmol/L; 95% CI: -0.25, 1.66 mmol/L) if currently obese.
conclusionsChildhood PM is associated with greater adult dysglycemia, whereas adulthood PM may have heterogeneous outcomes dependent on subsequent presence/absence of weight gain. Clinicians and public health managers should be aware of the long-term risk and intervene to promote some weight gain but prevent excess weight gain in people who were previously malnourished.
