Real-World Evidence of Health Outcomes Related to Lung Stereotactic Body Radiation Therapy in Brazil.

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
purposeStereotactic body radiation therapy (SBRT) is an effective option for patients with both early-stage and oligometastatic non-small-cell lung cancer (NSCLC). However, data from Latin America are limited. Therefore, the aim of this study was to investigate the real-world outcomes of applying SBRT for lung lesions in a Brazilian institution.
methodsThis study investigated a consecutive cohort of patients treated with SBRT for lung lesions (primary and metastasis). The study primary outcome was local control rates per lesion. Secondary outcomes included progression-free survival (PFS), overall survival (OS), and toxicity.
resultsBetween 2015 and 2019, a total of 216 patients received SBRT and were included in the study. The median follow-up was 24.5 months (5-70), primary NSCLC corresponded to 70% (n = 151) and nonprimary lung lesions to 30% (n = 65), respectively. Stage I NSCLC represented 56% (85 of 151) of the NSCLC cohort. The average number of fractions and total dose prescribed was 5 (3-10)/59 Gy (50-62 Gy). For stage I NSCLC (all lesions treated with a biologically effective dose [10] > 100 Gy), 2-year local control, OS, and PFS were 93.4%, 81.6%, and 80.7%, respectively. For stage IV lesions, if biologically effective dose (10) > 100 Gy or < 100 Gy, 2-year local control was 95.8/86.4% (
conclusionOur results indicate that SBRT is effective (high local control and acceptable toxicity) for treating malignant lung lesions in a real-world scenario in Latin America.
