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
backgroundPrincipal aims of this study were to evaluate, in frail immunocompromised patients, the willingness to receive the herpes zoster (HZ) vaccination and the impact of the in-hospital vaccination dedicated clinic on HZ vaccination adherence. MATERIALS AND
methodsA non-randomized quasi-experimental intervention study was conducted in Southern Italy among immunocompromised patients. Patients enrolled in the in-hospital vaccination dedicated clinic were included in the experimental group, while the control group consisted of patients recruited in the General Practitioners clinics.
resultsFrom April 2024 to March 2025, 369 patients were recruited, 183 of whom were included in the experimental group and 186 in the control group, The willingness to receive HZ vaccination was declared by 46.3% of subjects, and among those, 28.5% underwent vaccination. Logistic regression results showed that participants in the experimental group were significantly more likely to both declare willingness to receive vaccination (OR = 6.32; 95% CI 3.05-13.10) and to adhere to HZ vaccination (OR = 64.63; 95% CI 14.78-282.62).
conclusionsOur findings have shown that both willingness and adherence to HZ vaccination in immunocompromised subjects remain inadequate with respect to international targets and provide an effective model of integration between different professionals capable of promoting greater accessibility and adherence to HZ vaccination.
