Comparative analysis of clinical treatment outcomes: Breath-hold vs. free-breathing techniques in liver stereotactic body radiotherapy.
Article in Journal of medical imaging and radiation oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 aim of this study was to clarify the safety and efficacy of breath-hold irradiation in liver stereotactic body radiotherapy (SBRT).
methodsA retrospective analysis was conducted on 57 consecutive patients who received SBRT for hepatocellular carcinoma or liver metastases between 2013 and 2021. Breath-hold irradiation was implemented for patients treated after April 2020.
resultsThe median follow-up period for all patients was 16.4 months (IQR: 7.36-20.9). The 2-year overall survival rate was 64.4% (95% CI: 47.4-77.2), and the local control rate was 84.3% (95% CI: 69.7-92.3) for all patients. The 1-year overall survival was 80.0% (95% CI: 60.8-90.5) versus 82.0% (95% CI: 53.5-93.9) in the free-respiratory (FR) group versus the breath-hold (BH) group, respectively (P = 0.60). The 1-year local control rates were 78.1% (95% CI: 57.5-89.5) in the FR group and 95.7% (95% CI: 72.9-99.4) in the BH group, respectively (P = 0.16). Radiation-induced liver injury, defined by an escalation of ≥2 in Child-Pugh score, was observed in four patients within each group (FR 13% vs. BH 15%). There were no gastrointestinal adverse events of Grade 3 or higher.
conclusionBreath-hold irradiation can be safely administered and has demonstrated clinical potential in improving local control. Further research into dose escalation using breath-hold techniques is warranted.
