Article in BMJ open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT05195151 (Modulation of Immune Responses to COVID-19 Vaccination by an Intervention on the Gut Microbiota), which is not on this map. Cited by 1 paper.
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.

Abstract
introductionThe elderly are particularly vulnerable to morbidity and mortality from COVID-19, the disease caused by the SARS-CoV-2. Approximately 20% of the elderly showed no antibodies 3-5 months post-second dose of the COVID-19 vaccine. As probiotics have been shown to increase influenza-specific antibody levels post-influenza vaccination, we aim to reduce the percentage of participants without antibodies against the SARS-CoV-2 spike protein receptor-binding domain (anti-S1-RBD) at 6 months post-vaccination. METHODS AND ANALYSIS: Our study design is a double-blind randomised controlled trial, using intention-to-treat analysis. Eligible participants are a purposive sample of 688 adults aged 65-89 years, in Quebec, Canada, not diagnosed with COVID-19 in the 3 months prior to recruitment and who wish to receive a government-recommended mRNA booster (Pfizer-BioNTech, Moderna) vaccine. The intervention consists of one capsule/day of a probiotic dietary supplement of ETHICS AND DISSEMINATION: The study was approved by Research Ethics Board of the TRIAL REGISTRATION NUMBER: NCT05195151.
