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

introductionChemotherapy is the standard second-line treatment option for advanced biliary tract cancer (BTC), but its therapeutic efficacy is suboptimal. Disitamab vedotin (RC48) and lenvatinib have demonstrated promising efficacy in human epidermal growth factor receptor 2 (HER2)-positive BTC and other malignancies. In this study, we aim to evaluate the efficacy and safety of RC48 in combination with lenvatinib in second-line or above treatment for HER2-positive advanced BTC. METHODS AND ANALYSIS: This is a single-centre, single-arm, open-label, exploratory phase II clinical study in patients with HER2-positive unresectable locally advanced or metastatic BTC who have failed prior therapy. 31 patients will be enrolled in this study to receive the combination of RC48 and lenvatinib. The primary study endpoint is objective response rate, and the secondary study endpoints are disease control rate, duration of response, progression-free survival and overall survival. ETHICS AND DISSEMINATION: The study has received approval from the Medical Ethics Committee of Union Hospital, Tongji Medical College, Huazhong University of Science and Technology (approval No. (2023)0367-01). Results will be disseminated through publication in peer-reviewed journals and through other appropriate media channels. TRIAL REGISTRATION NUMBER: ChiCTR2300076406.
