Fecal microbiota transplantation promotes gut microbiome recovery in pediatric hematopoietic stem cell transplant recipients.
Article in Frontiers in microbiomes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. 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
Introduction: Hematopoietic stem cell transplantation (HSCT) profoundly disrupts the gut microbiome and may contribute to adverse post-transplant outcomes. Fecal microbiota transplantation (FMT) has emerged as a strategy to restore microbial diversity; however, data in pediatric HSCT recipients remain limited. Methods: We conducted a longitudinal analysis of 17 pediatric HSCT recipients who received FMT. Fecal samples were collected before FMT and at days 7, 14, and 30 after treatment. Gut microbiome composition was analyzed using 16S rRNA gene sequencing. Results: Baseline samples showed reduced microbial diversity and a dysbiotic microbial profile. Following FMT, microbial diversity increased progressively, with recovery evident from day 7 and stabilization by day 30. Taxonomic analyses demonstrated depletion of dysbiosis-associated genera and enrichment of beneficial short-chain fatty acid-producing taxa, including Conclusions: FMT was associated with progressive restoration of gut microbiome diversity and structure in pediatric HSCT recipients, supporting its potential role as a microbiota-based strategy to promote ecological recovery after HSCT.
