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

Effective therapeutic strategies for triple-negative breast cancer (TNBC) are still lacking. Clinical data suggest that a large number of TNBC patients cannot benefit from single immune checkpoint inhibitor (ICI) treatment due to the immunosuppressive tumour microenvironment (TME). Therefore, combination immunotherapy is an alternative approach to overcome this limitation. In this article, we combined two kinds of oncolytic adenoviruses with ICIs to treat TNBC in an orthotopic mouse model. Histopathological analysis and immunohistochemistry as well as multiplex immunofluorescence were used to analyse the TME. The immunophenotype of the peripheral blood and spleen was detected by using flow cytometry. Oncolytic adenovirus-mediated immune activity in a coculture system of lytic supernatant and splenocytes supported the study of the mechanism of combination therapy in vitro. Our results showed that the combination of oncolytic adenoviruses with anti-programmed cell death-ligand 1 (anti-PD-L1) and anti-cytotoxic T lymphocyte-associated antigen-4 (anti-CTLA-4) (aPC) can significantly inhibit tumour growth and prolong survival in a TNBC model. The combination therapy synergistically enhanced the antitumour effect by recruiting CD8
