Article in Investigational new drugs, 2019. 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 latex from Euphorbia tirucalli is used in Brazil as a folk medicine for several diseases, including cancer. Recently, we showed a cytotoxic activity of E. tirucalli euphol in a wide range of cancer cell lines. Moreover, we showed that euphol inhibits proliferation, motility and colony formation in pancreatic cancer cells, induces autophagy and sensitizes glioblastoma cells to temozolomide cytotoxicity. Herein, we report in vitro activity of three semi-synthetic ingenol compounds derived from E. tirucalli, IngA (ingenol-3-trans-cinnamate), IngB (ingenol-3-hexanoate) and IngC (ingenol-3-dodecanoate), against a large panel of human cancer cell lines. Antineoplastic effects of the three semi-synthetic compounds were assessed using MTS assays on 70 cancer cell lines from a wide array of solid tumors. Additionally, their antitumor potential was compared with known compounds of the same class, namely ingenol-3-angelate (Picato®) and ingenol 3,20-dibenzoate and in combination with standard chemotherapeutic agents. We observed that IngA, B, and C exhibited dose-dependent cytotoxic effects. Amongst the semi-synthetic compounds, IngC displayed the best activity across the tumor cell lines. In comparison with ingenol-3-angelate and ingenol 3,20-dibenzoate, IngC showed a mean of 6.6 and 3.6-fold higher efficacy, respectively, against esophageal cancer cell lines. Besides, IngC sensitized esophageal cancer cells to paclitaxel treatment. In conclusion, the semi-synthetic ingenol compounds, in particular, IngC, demonstrated a potent antitumor activity on all cancer cell lines evaluated. Although the underlying mechanisms of action of IngC are not elucidated, our results provide insights for further studies suggesting IngC as a putative therapy for cancer treatment.
