Comparing Oncologic Outcomes of Heat-Based Thermal Ablation and Cryoablation in Patients With T1a Renal Cell Carcinoma: A Population-Based Cohort Study From the SEER Database.
Article in Korean journal of radiology, 2024. 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
objectiveThere is controversy among different guidelines regarding the use of thermal ablation to treat clinical T1a renal cell carcinomas with tumor sizes ranging from 3.1-4 cm. Therefore, we compared oncological outcomes between heat-based thermal ablation (hTA) and cryoablation (CA) in patients with solid T1a renal cell carcinomas, including those with a tumor size ≤3 cm and a tumor size of 3.1-4 cm. MATERIALS AND
methodsWithin the Surveillance, Epidemiology, and End Results database (2000-2019), we identified patients with clinical T1a renal cell carcinomas that were histologically confirmed and treated with hTA or CA. After propensity score matching using a 1:1 ratio, the overall survival (OS) and cancer-specific survival (CSS) were estimated and compared between the two methods. Cancer-specific mortality (CSM) was also analyzed, considering other-cause mortality as a competing risk.
resultsOf the 3513 assessable patients, 1426 (40.6%) and 2087 (59.4%) were treated with hTA and CA, respectively. After propensity score matching, the hTA and CA groups included 1393 and 1393 patients, respectively. hTA was associated with shorter OS than CA with a hazard ratio of 1.17 (95% confidence interval, 1.04-1.32;
conclusionIn patients with clinical stage T1a renal cell carcinomas, hTA was comparable to CA in terms of CSS and CSM. However, hTA resulted in a slightly shorter OS than CA. Large-scale randomized clinical trials are required to obtain more robust evidence.
