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.

2 · The registry

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

backgroundRamadan fasting induces dietary and metabolic changes that may alter gut microbiota, but species-level effects are not well studied in Middle Eastern populations.

methodsFecal samples were collected from 30 healthy fasting and 30 non-fasting adults in Shiraz, Iran. Species-level bacterial abundance was quantified using culture-based isolation and SYBR Green qRT-PCR with universal and species-specific primers.

resultsBeneficial bacteria-including Bacteroides vulgatus (Ab.352 TH, NCBI PX796484), Bacteroides ovatus (Ab.353 TH, NCBI PX796487), and Odoribacter splanchnicus (Ab.354 TH, NCBI PX796490)-were significantly increased in fasting individuals, while pathobionts such as Prevotella stercorea (Ab.355 TH, NCBI PX796493), Alistipes putredinis (Ab.356 TH, NCBI PX796496), Collinsella aerofaciens (Ab.357 TH, NCBI PX796499), and Enterobacter cloacae (Ab.358 TH, NCBI PX796500) were reduced.

conclusionRamadan fasting promotes a gut microbiota enriched in SCFA-producing beneficial bacteria and depleted of inflammation-associated pathobionts, suggesting species-specific microbial adaptations that may enhance gastrointestinal, immunological, and systemic health.
