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
Purpose: To analyze the oncological outcome in elderly (>70 years) prostate cancer after high-dose rate brachytherapy (HDB) boost. Materials/methods: In this retrospective study, patients with intermediate (IR) and high-risk (HR) prostate cancer underwent external beam radiation therapy (EBRT) followed by HDB boost with/without androgen deprivation therapy (ADT). The impact of age (≤70y vs. > 70y) was investigated. Oncological outcome focused on biochemical relapse-free survival (bRFS), cause-specific (CSS) and overall survival (OS). Late genito-urinary (GU) and gastro-intestinal (GI) toxicities were investigated. Results: From 07/08 to 01/22, 518 pts received a HDB boost, and 380 were analyzed (≤70y:177pts [46.6%] vs. > 70y:203pts [53.4%]). Regarding NCCN classification, 98 pts (≤70y: 53pts; >70y: 45pts; p = 0.107) and 282 pts (≤70y: 124pts; >70y: 158pts; p = NS) were IR and HR pts respectively. Median EBRT dose was 46 Gy [37.5-46] in 23 fractions [14-25]. HDB boost delivered a single fraction of 14/15 Gy (79%). ADT was used in 302 pts (≤70y: 130pts; >70y: 172pts; p = 0.01). With MFU of 72.6 months [67-83] for the whole cohort, 5-y bRFS, 5-y CSS and 5-y OS were 88% [85-92], 99% [97-100] and 94% [92-97] respectively; there was no statistical difference between the two age groups except for 5-y CSS (p = 0.05). Late GU and GI toxicity rates were 32.4% (G ≥ 3 7.3%) and 10.1% (no G3) respectively. Conclusions: For IR and HR prostate cancers, HDB boost leads to high rates of disease control with few late G ≥ 3 GU/GI toxicities. For elderly pts, HDB boost remains warranted mainly in HR pts, while competing comorbidity factors influence OS.
