Effects of potato plants expressing a barley cystatin on the predatory bug Podisus maculiventris via herbivorous prey feeding on the plant.
Article in Transgenic research, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 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 aim of this study was to assess the effects of potato plants expressing a barley cystatin on a potentially cystatin-susceptible natural enemy by predation on susceptible and non-susceptible preys feeding on the plant. We have focussed on the impact of the variant HvCPI-1 C68 --> G, in which the only cysteine residue was changed by a glycine, on the growth and digestive physiology of the Colorado potato beetle (CPB), Leptinotarsa decemlineata, and the Egyptian cotton leafworm (ECW), Spodoptera littoralis. Moreover, we have studied the prey-mediated effects of the barley cystatin at the third trophic level, using the predatory spined soldier bug (SSB), Podisus maculiventris, as a model. Feeding trials conducted with CPB larvae reared on transgenic potato plants expressing the C68 --> G variant resulted in significantly lower weight gains compared to those fed on non-transformed (NT) plants. On the contrary, larger weight gains were obtained when ECW larvae, that lack digestive cysteine proteases, were reared on transgenic potato expressing the cystatin, as compared to larvae fed on NT plants. No negative effects on survival and growth were observed when SSB nymphs were exposed to HvCPI-1 C68 --> G by predation on either CPB or ECW larvae reared on transgenic potato plants expressing the barley cystatin, despite the fact that the inhibitor suppressed in vitro gut proteolysis of the predatory bug. To investigate the physiological background, biochemical analysis were carried out on guts of insects dissected at the end of the feeding assays.
