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
backgroundElectrochemotherapy (ECT) is a local nonsurgical effective tumor treatment in the hand of the clinician for the treatment of patients with liver tumors or metastases. The study aimed to test the technical feasibility and safety of intra-arterial (i.a.) bleomycin administration compared to the established intravenous (i.v.) administration in percutaneous electrochemotherapy (pECT). Furthermore, the equivalence hypothesis was tested between the 2 modalities in terms of local short-term response and progression-free survival. PATIENTS AND
methodsForty-four patients have been recruited and treated by pECT for hepatocellular carcinoma, cholangiocarcinoma and liver metastatic lesions from cancers of different origin: 18 were treated with standard i.v., 26 with bleomycin i.a. administration.
resultsThe 2 groups were similar for anagraphic and anamnestic data, as well as for most relevant disease specific characteristics. Technical success of the treatment was obtained in 95% and 100% of patients in i.v. and i.a. groups respectively. Short-term local response was similar in the 2 groups with a slightly higher complete remission (CR) rate in the i.a. group. There were 61.9% CR, 23.8% partial remission (PR), 4.8% stable disease (SD) in the i.v. group, and 80.6%, CR 12.9% PR, 3.2% PD (p = 0.3454). One-year progression free survival was 60% (C.I. 33%-88%) in the i.v. group and 67% (C.I. 42%-91%) in the i.a. group (p = 0.5849).
conclusionsThe results of this study confirmed the safety and feasibility of super-selective i.a. bleomycin administration. Analysis of local response and progression free survival confirmed the equivalence hypothesis of the new modality compared to standard i.v. administration in the treatment of primary and secondary liver malignancies by pECT.
