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

Cancer patients require a tailored vaccination strategy. This study aims to assess the vaccination status of cancer patients, evaluate disease incidence and severity in vaccinated individuals, identify reasons for noncompliance with guideline-recommended vaccines, and explore vaccine hesitancy. A cross-sectional survey, including 36 multiple-choice and 6 open-ended questions, was conducted in across Turkey. A total of 506 patients participated between September 1, 2024, and December 31, 2024. Among the participants, 59% (n = 302) were receiving active treatment. At the time of diagnosis, 90.5% did not have an ongoing vaccination program. Coronavirus Disease 2019 (COVID-19) (86.2%) and influenza (22.0%) were the most frequently received vaccines before treatment.The most common reason for not being vaccinated (except for COVID-19) was the absence of a medical recommendation. Higher education levels were associated with increased vaccination rates for hepatitis B, influenza, 13-valent pneumococcal conjugate vaccine (PCV13), and 23-valent pneumococcal polysaccharide vaccine (PPSV23)
