Brachytherapy vs external beam therapy among NSCLC patients undergoing limited surgical resection.
Article in Journal of cancer research and clinical oncology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo compare brachytherapy to external beam radiation therapy (EBRT) with respect to overall survival (OS) and disease-specific survival (DSS) among NSCLC patients undergoing limited surgical resection.
methodsAll cases of T1-4 N0 M0 NSCLC undergoing limited resection and either brachytherapy or EBRT diagnosed between 2004 and 2014 were extracted from the Surveillance, Epidemiology, and End Results database. Chi-square test and Fisher's exact analysis were used to analyze categorical variables while Student's t-test was used to analyze continuous variables. Univariate analysis to assess for differences in survival with respect to covariates was performed with the log-rank test. Multivariable analysis was performed with Cox proportional hazards regression models among the entire cohort and after sub-stratification by T stage.
resultsAmong 543 patients, 471 underwent EBRT and 72 underwent brachytherapy. Brachytherapy demonstrated improved OS and DSS on univariate analysis as compared to EBRT (p < 0.05). Cox regression also demonstrated improved OS and DSS with brachytherapy (HR 0.604; 95% CI [0.380; 0.961] and HR 0.524; 95% CI [0.303; 0.908], respectively). Sub-cohort analysis demonstrated significant improvement in survival only among patients with T1 disease with similar survival between brachytherapy and EBRT among higher stage disease.
conclusionsPatients undergoing brachytherapy for T1-T4, N0, M0 NSCLC demonstrated at least similar survival as compared to those undergoing EBRT among patients undergoing limited resection. Improved survival was demonstrated among patients with T1 disease.
