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
Despite advancements of diagnosis and multimodality therapies in esophageal squamous-cell carcinoma (ESCC), the survival is still unsatisfactory. Therefore, it is urgent to identify novel targets for efficient therapeutic strategies. Herein, we identify a fusion gene between PLEKHA1 and TACC2 generated by chromosomal rearrangement by performing RNA sequencing from ESCC tissues. PLEKHA1-TACC2 transcripts are present in ESCC (66/404, 16.3%) and head and neck squamous cell carcinoma (58/402, 14.4%) tissues, correlated with poor prognosis of patients. Mechanistically, the fusion proteins upregulate the EphA2/AKT/MMP2 signaling pathway and promote vascular mimicry formation by reducing the ubiquitylation of EphA2. Moreover, EphA2 inhibitors dasatinib and ALW II-41-27 remarkably suppress the progression of tumors expressing PLEKHA1-TACC2 in vivo. Functionally, PLEKHA1-TACC2 fusion and Trp53 deletion significantly increases tumor incidence, tumor multiplicity, and mouse mortality in transgenic ESCC mouse model, which could be suppressed by regorafenib, a EphA2 inhibitor approved by FDA in solid tumors. Together, our data indicate that PLEKHA1-TACC2 fusion protein has oncogenic activities and serves as a promising prognosis marker and therapeutic target.
