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
LAG3 plays a regulatory role in immunity and emerged as an inhibitory immune checkpoint molecule comparable to PD-L1 and CTLA-4 and a potential target for enhancing anti-cancer immune responses. We generated 3D cancer cultures as a model to identify novel molecular biomarkers for the selection of patients suitable for α-LAG3 treatment and simultaneously the possibility to perform an early diagnosis due to its higher presence in breast cancer, also to achieve a theragnostic approach. Our data confirm the extreme dysregulation of LAG3 in breast cancer with significantly higher expression in tumor tissue specimens, compared to non-cancerous tissue controls. LAG3 blockade inhibited proliferation of in vitro and ex vivo 3D human organoids and immune micro-environment through both a decrease of PD-L1, TIM-3 and CTLA4 expression and an increased production of several pro-inflammatory cytokines (IFNγ, IL-12, IL-6, IL-1β, TNFα) and EMT markers. These effects trigger a more permissive anti-tumor immune reaction, recruiting immune cells to the tumor sites, boosting the anti-tumor response. LAG3 acts as an immunosuppressive molecule in breast cancer, inhibiting T CD8 + cell proliferation and cytokine production by T cells. We proposed the modulation of a novel checkpoint molecule, such as LAG3, as potential biomarkers associated to a rapid diagnosis.
