1 · What the graph read from it

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.

2 · The registry

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

Importance: The long-term outcomes of transcatheter arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) are not determined. Objective: To report the long-term outcomes of TACE-RFA. Design, Setting, and Participants: This cohort study analyzed long-term follow-up data from a phase 3 randomized clinical trial of adults with early HCC conducted from October 2006 to June 2009. Participants were randomly assigned to the TACE-RFA group or the RFA group in a 1:1 ratio and followed up approximately 6 years after the trial was closed. Data analysis was performed March 2020. Exposure: In the TACE-RFA group, TACE was performed first, and RFA was done 2 weeks later. Main Outcomes and Measures: Overall survival (OS) and recurrence-free survival (RFS). Results: Of 189 patients who were included (mean [SD] age, 54.3 [12.0] years; 146 [77.2%] men), 94 and 95 patients were assigned to the TACE-RFA group and RFA group, respectively, with their baseline characteristics well matched. Three patients in each group were lost to follow-up. The 5-year and 7-year OS rates for the TACE-RFA group vs the RFA group were 52.0% and 36.4% vs 43.2% and 19.4%, respectively (hazard ratio [HR], 0.55; 95% CI, 0.39-0.78; P = .001). The 5-year and 7-year RFS rates for the TACE-RFA group vs the RFA group were 41.4% and 34.5% vs 27.4% and 18.1%, respectively (HR, 0.66; 95% CI, 0.49-0.89; P = .007). On subgroup analysis comparing patients who had tumors larger than 3 cm with those who had tumors 3 cm or smaller, the OS and RFS survival rates in the TACE-RFA group (HR, 3.20; 95% CI, 1.91-5.35, P < .001) were significantly better than those in the RFA group (HR, 2.03; 95% CI, 1.30-3.17; P = .002). Conclusions and Relevance: In this cohort study, combined RFA and TACE was associated with better survival than RFA alone on long-term follow-up. Patients with tumors 3 cm or smaller did not benefit as well as patients with tumors larger than 3 cm from the combined treatment.
