Fig. 1From: Study of Environmental Enteropathy and Malnutrition (SEEM) in Pakistan: protocols for biopsy based biomarker discovery and validationConceptual framework for hypothesis testing in SEEM. The severity of clinical phenotypes in Matiari children with wasting and suboptimal response to nutritional rehabilitation will highly correlate with the histopathological appearance of duodenal biopsies; duodenal and fecal dysbiosis; perturbation of duodenal gene expression profiles; systemic biochemical profiles; and children’s genotypes. The image in the top right panel demonstrates the histological changes observed in the small intestine as environmental enteropathy progresses.
