1 · What the graph read from it

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.

2 · The registry

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

Genetic engineering of the filamentous fungus Aspergillus oryzae still requires more suitable selection markers for fungal transformation. Our previous work has shown that Agrobacterium tumefaciens-mediated transformation (ATMT) based on the uridine/uracil auxotrophic mechanism with pyrG as the selection marker is very efficient for gene transfer in A. oryzae. In the present study, we delete the hisB gene, which is essential for histidine biosynthesis, in A. oryzae via homologous recombination and demonstrate that hisB is a reliable selection marker for genetic transformation of this fungus. Under optimal conditions, the ATMT efficiency of the histidine auxotrophic A. oryzae reached 515 transformants per 10
