A truncated apoptin protein variant selectively kills cancer cells.
Article in Investigational new drugs, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Apoptin is a nonstructural protein encoded by one of the three open reading frames of the chicken anemia virus genome. It has attracted a great deal of interest due to its ability to induce apoptosis in multiple transformed and malignant mammalian cell lines without affecting primary and non-transformed cells. However, the use of Apoptin as an anticancer drug is restricted by its strong tendency to aggregate. A number of methods to overcome this problem have been proposed, including transduction techniques to deliver the Apoptin gene into tumor cells, but all such methods have certain drawbacks. Here we describe that a truncated variant of Apoptin, lacking residues 1 to 43, is a soluble, non-aggregating protein that maintains most of the biological properties of wild-type Apoptin when transfected into cells. We show that the cytotoxic effect of this variant is also present when it is added exogenously to cancer cells, but not to normal cells. In addition to the interest this protein has attracted as a promising therapeutic strategy, it is also an excellent model to study the structural properties of Apoptin and how they relate to its mechanism of action.
