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 evaluate the survival benefit of combining radiotherapy with surgery in locally advanced esophageal squamous cell carcinoma (ESCC) patients aged over 65.
methodsUsing the SEER database, we selected patients age ≥ 65 years that were diagnosed as locally advanced ESCC during 2004-2013. Cancer-specific survival (CSS) was examined using the Kaplan-Meier analysis and compared by the log-rank test. Univariable and multivariable Cox proportional hazard models were established to identify possible prognostic factors.
resultsA total of 972 cases were included in the study. For surgical patients aged 65-79 years, 74 patients (32.9%) were treated by surgery alone and 122 patients (54.2%) had received additional neoadjuvant radiotherapy (NRT). NRT + surgery was associated with improved CSS comparing with surgery alone (HR, 0.58; 95%CI, 0.39 to 0.85; P = 0.005). In subgroup analysis, NRT was associated with improved CSS for patients aged 65-74 years (2-year CSS 56.6% versus 39.6%, P = 0.026). No significant differences of progonosis was observed for different treatment groups in 75-79 years patients (P = 0.972).
conclusionsIn this SEER-based study, the addition of neoadjuvant radiotherapy before surgery was associated with improved CSS for locally advanced ESCC patients aged 65 to 74 years.
