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
IntroductionThe optimal management of localized prostate cancer (PCa) in the "oldest-old" demographic presents a unique clinical challenge, requiring a careful balance between oncological control and the preservation of quality of life. This study aims to evaluate the safety, toxicity profile, and clinical outcomes of moderately hypofractionated helical tomotherapy (HT) in a cohort of patients aged 75 years and older with localized PCa.Materials and MethodsIn this retrospective cohort study, we analyzed 51 consecutive patients with a median age of 79 years treated between 2016 and 2022. All patients received 69 Gy in 25 fractions (2.76 Gy/fraction) via the HT platform. Risk stratification was performed using the D'Amico classification, revealing that the majority were high-risk (52.9%) or intermediate-risk (43.1%). Clinical outcomes included biochemical relapse-free survival (BRFS), cancer-specific survival (CSS), and overall survival (OS). Toxicity grading followed CTCAE v4.0 criteria, and Quality of Life (QoL) was evaluated through the International Prostate Symptom Score (IPSS) and a single-item index.ResultsAt a median follow-up of 38 months, the 5-year BRFS, CSS, and OS rates were 83.3%, 80.1%, and 68.8%, respectively. Acute Grade 2 genitourinary and gastrointestinal toxicities occurred in 25.5% and 27.5% of the subjects. Late Grade 3 complications were rare (1 GU, 4 GI). Significant longitudinal improvements in IPSS and QoL were observed within 3 months post-treatment (
