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

Emerging evidence indicates gut microbiota is essential to chronic kidney disease (CKD) progression. This study investigated the association between gut microbiota profiles, plasma trimethylamine-N-oxide (TMAO), and circulating inflammatory markers in CKD patients according to dietary patterns, particularly low-protein, high-fiber (LP-HF) versus high-protein, low-fiber (HP-LF) diet. In this cross-sectional study, patients with non-dialysis CKD and healthy subjects were enrolled. Dietary patterns among participants were assessed using three-day diet records with detailed nutrient analysis. The 16 S ribosomal RNA sequencing was conducted to examine fecal gut microbiota composition. Plasma samples were analyzed for TMAO concentration and cytokine levels. A total of 135 CKD patients were recruited. A distinct shift in gut microbiota composition in CKD patients was observed compared to 19 healthy controls, particularly a significant reduction of short-chain fatty acid (SCFA)-producing bacteria. TMAO and several cytokine levels were significantly elevated in CKD patients compared to healthy subjects. Within CKD, patients with LP-HF diet displayed a greater abundance of SCFA-producing bacteria, such as the Lachnospiraceae NK4A136 group and Eubacterium ruminantium group, than those with the HP-LF diet. The HP-LF subgroup showed enriched proteolytic bacterial genera such as Klebsiella. The HP-LF subgroup also exhibited significantly higher plasma levels of TMAO, interleukin (IL)-18, and monocyte chemoattractant protein-1 (MCP-1). CKD patients displayed marked alterations in gut bacterial composition compared to healthy controls. Our results also highlighted the potential advantages of adopting a high fiber-rich and low-protein diet intake in reducing gut dysbiosis in CKD patients.
