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

The gut microbiome has a critical role in shaping the patient's immune response and influencing the efficacy of anticancer immunotherapy. Emerging evidence suggests that modulating the gut microbiome through interventions such as faecal microbiota transplantation, probiotics, prebiotics and lifestyle modifications may enhance therapeutic outcomes. Consequently, drug development efforts in immuno-oncology have expanded to explore microbiome-based therapeutic strategies. In this Review, we examine the rationale for targeting the microbiome in cancer treatment, highlighting key advances in clinical microbiome characterization and their implications for immunotherapy. We discuss findings from recent clinical trials evaluating microbiome-based interventions and address the challenges associated with translating these approaches into clinical practice. Finally, we outline future directions for the development and integration of microbiome-targeted therapies in oncology, with a focus on optimizing efficacy, safety and patient stratification strategies.
