Review in Cell host & microbe, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07195006 (Early Life Diarrhoea Episode), which is not on this map. Cited by 24 papers.

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.

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.

Abstract

Forty-five percent of deaths among children under 5 years of age are associated with undernutrition. Globally, almost 200 million children exhibit the two major forms of undernutrition-wasting (low weight-for-height) or stunting (low height-for-age), with many affected by both. Undernutrition is not due to food insecurity alone. Growing evidence indicates that perturbed postnatal gut microbiome development contributes to its pathogenesis. This perspective focuses on defining and repairing these defects in gut microbiome development. We describe an approach that involves the analysis of well-phenotyped human cohorts, followed by preclinical studies using gnotobiotic animals colonized with microbiota from these cohorts. Additionally, these models can be used to identify therapeutic targets and candidates that can then be tested clinically. Furthermore, introducing pretreatment microbiota from trial participants into gnotobiotic animals and re-enacting trial conditions allow mechanisms to be dissected. We highlight these recent advances as well as gaps in existing knowledge that present opportunities for future research.
