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

This case describes an 81-year-old male patient with poorly differentiated lung adenocarcinoma, complicated by severe chronic obstructive pulmonary disease (COPD) and a history of coronary stenting. The patient underwent CyberKnife (Accuray Inc., Madison, WI, United States) stereotactic body radiotherapy (SBRT) with synchrony respiratory tracking and staged radiotherapy. The patient received staged radiotherapy delivered in two sequential phases: phase I (30 Gy in three fractions) was administered from November 18 to 24, 2022, followed by phase II (30 Gy in three fractions) initiated on February 20, 2023, after a 12-week intermission for therapeutic response assessment and normal tissue recovery. The cumulative prescription totaled 60 Gy in six fractions (equivalent dose in 2-Gy fractions (EQD2) = 120 Gy, α/β = 10), with strict adherence to organ-at-risk (OAR) constraints. Through fiducial marker implantation and dynamic dose optimization, the ipsilateral lung V20 was reduced from 3.35% to 1.63%. No severe treatment-related toxicities (≥ grade 2) were observed during or after the treatment period. At a three-month follow-up, the tumor volume decreased by 79% (117.04 cm³ → 24.26 cm³), demonstrating significant local control. This case provides a practical reference for personalized radiotherapy in elderly patients with cardiopulmonary comorbidities.
