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
backgroundPatients with immune-mediated rheumatic diseases (IMRD) are at increased risk for infections due to both disease-related immune dysregulation and immunosuppressive therapy. Despite the benefits of vaccination, immunization rates in this population remain suboptimal, often due to concerns about safety, efficacy, and their potential for inducing disease flare. Regional-specific guidelines are necessary to address the particular epidemiological issues and aspects of the healthcare systems, especially in countries like Brazil.
objectiveTo provide updated, evidence-based, and nationally relevant recommendations on vaccination in adult patients with IMRD in Brazil, focusing on immunogenicity, safety and disease activity outcomes.
methodsA multidisciplinary task force from the Brazilian Society of Rheumatology conducted a systematic review and meta-analysis of studies addressing eleven clinical questions related to vaccine safety and efficacy in IMRD. Studies were selected using predefined PICO criteria. Risk of bias was assessed using JBI tools, and the certainty of evidence was evaluated with the GRADE approach. Statements were developed and submitted to a Delphi-based voting process; consensus was achieved if ≥80% of the panelists voted “agree” or “strongly agree” for all the statements.
resultsEleven recommendations were developed based on a systematic review of the literature, with meta-analyses conducted when appropriate. Inactivated vaccines demonstrated a favorable safety profile, with low flare rates and no significant increase in disease activity, even under immunosuppression. Live attenuated vaccines, including yellow fever, were considered safe when administered according to timing protocols. Immunogenicity may be reduced in patients receiving methotrexate, mycophenolate, corticosteroids, rituximab, and JAK inhibitors, although this does not appear to compromise clinical protection in most cases. Temporary treatment interruption was associated with improved immunogenicity in selected contexts, but without consistent evidence of clinical benefit and with potential risks related to disease control. Specific guidance was provided for influenza and hepatitis B vaccination, as well as for prioritizing vaccination before initiating immunosuppression whenever feasible. Statements also addressed the approach to revaccination and post-vaccination serologic testing. Despite the overall very low to moderate certainty of evidence, most recommendations reached strong consensus (≥80% agreement). Shared decision-making and individualized strategies were emphasized across all scenarios.
conclusionThese recommendations offer tailored guidance for improving vaccination strategies in IMRD patients in Brazil. Given the heterogeneity of evidence, clinical decisions should be individualized, considering disease activity, treatment regimen, vaccine availability, and patient preferences. Shared decision-making is essential in all scenarios to enhance vaccine uptake and align preventive care with patient-centered management.
