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
Trastuzumab-resistance is still a major challenge in treating patients with HER2 positive breast cancer. In this study, we tried to overcome transtuzumab-resistance by examining the therapeutic efficacy of third generation anti-HER2 chimeric antigen receptor (CAR)-T cells alone and in combination with PD1 blockade against HER2 positive and trastuzumab-resistance breast cancer cells in vitro and xenograft model. The anti-HER2 CAR-T cells were generated by infecting CD3/CD28 activated peripheral blood mononuclear cells with lentivirus expressing third generation anti-HER2 CAR. Anti-HER2 CAR-T cells were specifically targeted to HER2 positive BT474 and trastuzumab resistant HCC1954 cells compared with HER2 negative breast cancer cells. Results from ELISA revealed that the secretion of IL-2 and IFN-γ was increased in anti-HER2 CAR-T cells after being co-cultured with HCC1954 cells, and was further increased with the addition of anti-PD1 antibody in the co-culture system. Furthermore, data from lactate dehydrogenase assay showed that anti-HER2 CAR-T cells displayed a potent cytotoxicity against HCC1954 and BT474 cells. Addition of anti-PD1 antibody further enhanced the cytotoxicity of anti-HER2 CAR-T cells against HCC1954 cells. Lastly, injection of anti-HER2 CAR-T cells significantly reduced the growth of HCC1954 xenograft tumors. Combining anti-HER2 CAR-T cells with anti-PD1 antibody further impaired the growth of HCC1954 tumors. The present results indicate that anti-HER2 CAR-T cells have therapeutic efficacy against trastuzumab resistant breast tumors and addition of the PD1 antibody can further enhance the therapeutic effect of anti-HER2 CAR-T cells. Thus, third generation anti-HER2 CAR-T cells along with PD1 blockade is a potential therapy to overcome trastuzumab resistance of breast cancer.
