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

purposeThis systematic review and meta-analysis compares the efficacy of three combination therapies, including transarterial chemoembolization (TACE) with radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation (CRA) for the treatment of patients with hepatocellular carcinoma (HCC).

methodsOnline databases, including Scopus, Web of Science, PubMed, Embase, CNKI, Google Scholar, and Cochrane Library were searched.

resultsForty-two studies with 5468 pooled patients (TACE + RFA: 21 studies with 3398 patients, TACE + MWA:14 studies with 1477 patients, and TACE + CRA: 7 studies with 593 patients) reported combination therapy versus TACE alone. The TACE + MWA subcohort had the best odds of long-term overall survival (OR 4.81, 95% CI 1.44, 16.08, P = 0.011) and objective response rate (OR 3.93, 95% CI 2.34, 6.61, P < 0.001) compared with the other two combination subcohorts. The TACE + RFA and TACE + MWA subcohorts had approximately similar odds of 1-year recurrence-free survival (OR 5.21, 95% CI 2.13, 12.75, P < 0.001 and OR 4.61, 95% CI 1.70, 12.51, P = 0.003, respectively). The disease control rate was similar between the TACE + MWA and TACE + CRA subcohorts (OR 4.01, 95% CI 2.66, 6.04, P < 0.001 and OR 4.05, 95% CI 1.68, 9.74, P = 0.002) but greater than the TACE + RFA subcohort (OR 3.23, 95% CI 2.14, 4.86, P < 0.001).

conclusionOverall, the TACE + MWA subcohort had the best efficacy and outcomes, especially for younger patients (less than 60-year-old) with tumor size of ≤ 3 cm, compared with the TACE + RFA or TACE + CRA subcohorts.
