Development and expert appraisal of a lifestyle questionnaire for microbiome host metadata.
Article in Frontiers in cellular and infection microbiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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: Lifestyle information can help contextualize variation in the human gut microbiome, but its collection and operational definitions differ across studies. We developed a candidate questionnaire combining diet, physical activity and sleep for microbiome host metadata and undertook an initial appraisal by Italian experts. Candidate content was informed by a focused narrative literature appraisal and established lifestyle-assessment frameworks. Methods: Seventeen experts were invited and nine responded (53%). In a single anonymous rating round, experts assessed the relevance of 37 candidate items on a five-point scale. The prespecified agreement criterion was at least 70% of respondents assigning a rating of 4 or 5, corresponding to at least seven of nine experts. Results: Twenty-five items (67.6%) met this criterion: 18 of 23 dietary items (78.3%), six of eight physicalactivity items (75.0%), and one of six sleep items (16.7%). Twelve items remained exploratory. Discussion: These findings provide an initial prioritization of candidate lifestyle metadata within an Italian specialist network. They do not establish a stable iterative Delphi consensus, instrument reliability, construct validity, or associations between questionnaire responses and microbiome outcomes. Participant testing, operational refinement and empirical evaluation are required before research deployment or potential use in fecal microbiota transplantation donor characterization.
