The Kynurenine/Tryptophan Ratio and Glioblastoma Patients Treated with Hsppc-96 Vaccine.
Article in Immunotherapy (Los Angeles, Calif.), 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
The discovery that immunotherapy is a clinically-relevant approach for the treatment of malignant tumors is revolutionizing patient care. In adults diagnosed with glioblastoma (GBM), an aggressive and incurable primary brain tumor, autologous HSPPC-96 vaccination provides a significant increase in overall survival. However, all GBM patients eventually succumb to their disease, providing rationale for discovering new methods that proactively identify individuals that will respond, optimally. Of the immunosuppressive mediators that contribute to the inhibition of productive tumor immunity, indoleamine 2,3 dioxygenase 1 (IDO1), a rate-limiting enzyme that catabolizes tryptophan (Trp) into kynurenine (Kyn), has been demonstrated to be expressed at elevated levels in patients with malignant glioma. Recently, our group determined that a correlation exists between peripheral blood Trp and Kyn levels in GBM patients and the association with overall survival after HSPPC-96 treatment. Our findings indicate that the Kyn/Trp ratio may be a useful benchmark for identifying GBM patients with a higher likelihood to survive longer after vaccination. The relevance to future clinical trials, the limitations of brain tumor models to address these findings and the role of IDO1 versus tryptophan dioxygenase (TDO) in the maintenance of peripheral Trp and Kyn levels, is discussed.
