Preliminary comparing the toxicities of the hybrid cry1Acs fused with different heterogenous genes provided guidance for the fusion expression of Cry proteins.
Article in World journal of microbiology & biotechnology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 2 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
In order to provide guidance for selecting suitable heterogenous gene that can efficiently enhance toxicity or broaden insecticidal spectrum of Cry1Ac through fusion expression, two hybrid cry1Acs fused with chitinase-encoding gene tchiB and neurotoxin gene hwtx-1 respectively were constructed and their toxicities were compared. A Bacillus thuringiensis strain harboring the cry1Ac gene in vector pHT315 was used as control. Bioassay revealed that LC(50) (after 72 h) of Cry1Ac protoxin was 41.01 μg mL(-1), while the hybrid cry1Acs fused with tchiB and hwtx-1 were 4.89 and 23.14 μg mL(-1), which were 8.23- and 1.77-fold higher than Cry1Ac protoxin in terms of relative toxicity respectively. Both fusion crystals had a higher toxicity than the original Cry1Ac protein and the toxicity of hybrid cry1Acs fused with hwtx-1 experienced a more significant increase than that fused with tchiB.
