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
purposeThe prognoses of T1a and T1b glottic cancers are still controversial. This study aimed to compare the prognosis difference between the two groups based on the population-based Surveillance, Epidemiology, and End Results database (SEER).
methodsData for patients with T1a or T1b glottic cancers were extracted from the SEER database. The bias between T1a and T1b glottic cancers was minimized with Propensity Score Matching (PSM), and disease-specific survival (DSS) was analyzed using the Kaplan-Meier method, log-rank test, and Cox proportional hazards models.
resultsA total of 5,272 patients were extracted from the database, including 847 patients with T1b glottic cancer that were 1:1 propensity score-matched with patients with T1a glottic cancer. After propensity score-matching, there was no statistical difference in disease-specific survival between T1a and T1b patients, whilst survival was impaired by old age. However, on the multivariate analysis, the T1a stage was associated with improved DSS compared with the T1b stage.
conclusionOur analysis showed that T1a glottic cancers didn't have a significantly better prognosis compared with T1b after PSM. However, the DSS of T1a patients is superior to that of T1b patients in multivariate analysis.
