Characterization of microbiota in acute leukemia patients following successful remission induction chemotherapy without antimicrobial prophylaxis.
Article in International microbiology : the official journal of the Spanish Society for Microbiology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
purposeIn the present study, we characterized the microbiomes of acute leukemia (AL) patients who achieved complete remission following remission induction chemotherapy (RIC) as outpatients, but who did not receive antimicrobials to treat or prevent febrile neutropenia.
methodsSaliva and stool samples from 9 patients with acute myeloid leukemia, 11 patients with acute lymphoblastic leukemia, and 5 healthy controls were subjected to 16S ribosomal RNA sequencing at baseline and at 3 months following RIC. Only patients who achieved remission at 3 months post-treatment were included. We excluded anyone who used antimicrobials within 2 months of enrollment or at any time during the study period.
resultsAt baseline, the relative abundances of species of Prevotella maculosa (P=0.001), Megasphaera micronuciformis (P=0.014), Roseburia inulinivorans (P=0.021), and Bacteroides uniformis (P=0.004) in saliva and Prevotella copri (P=0.002) in the stools of controls were significantly higher than in AL patients. Following RIC, the relative abundances of Eubacterium sp. oral clone DO008 (P=0.012), Leptotrichia sp. oral clone IK040 (P=0.002), Oribacterium sp. oral taxon 108 (P=0.029), Megasphaera micronuciformis (P=0.016), TM7 phylum sp. oral clone DR034 (P<0.001), Roseburia inulinivorans (P=0.034), Actinomyces odontolyticus (P=0.014), Leptotrichia buccalis (P=0.005), and Prevotella melaninogenica (P=0.046) in saliva and Lactobacillus fermentum (P=0.046), Coprococcus catus (P=0.050), butyrate-producing bacterium SS3/4 (P=0.013), and Bacteroides coprocola (P=0.027) in the stools of AL patients were significantly greater than in controls.
conclusionFollowing RIC, several taxa are changed in stool and salvia samples of AL patients. Our results warrant future large-scale multicenter studies to examine whether the microbiota might have an effect on clinical outcomes of AL patients.
