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

Delta-endotoxins are produced by Bacillus thuringiensis (Bt) and have their main application in agriculture to manage insect crops and as antimicrobial. Its large scale production is limited by oxygen availability during Bt fermentation since delta-endotoxin synthesis requires high oxygen level. Therefore, it requires the enhancement of the agitation speed and air flow rate, which could be solved by adding an oxygen vector. So, the objective was to evaluate the use of oxygen vectors (soybean, corn and sunflower oil) on the enhancement of delta-endotoxin production and its toxicity against Spodoptera frugiperda and pathogenic microorganisms. In this way, the effects of oils on fermentation were studied from a 2
