Diatraea saccharalis harbors microorganisms that can affect growth of sugarcane stalk-dwelling fungi.

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
Diatraea saccharalis (Fabricius, 1794) (Lepidoptera: Crambidae), the sugarcane borer, spends most of its life cycle inside the galleries it burrows into sugarcane stalk, where two rot-causing fungi Colletotrichum falcatum (Went, 1893) and Fusarium verticillioides (Nirenberg, 1976) are commonly found. Results have shown that microbiota harbored by D. saccharalis inhibits the growth of F. verticillioides and C. falcatum. D. saccharalis larvae were collected from chemical-free field plants, and yeast and bacteria from third and fourth-instar D. saccharalis regurgitate were isolated onto appropriate media. The percentage of F. verticillioides and C. falcatum mycelial growth inhibition was recorded. Out of 32 yeast isolates, 9 exerted 30 to 40% growth inhibition of C. falcatum or F. verticillioides. When 24 bacterial isolates were confronted with rot-causing fungi, six inhibited C. falcatum growth by 30 to 60%, and 24 isolates inhibited 30 to 60% of F. verticillioides growth. Bacteria and yeast isolates were identified through DNA sequencing of part of 16S rDNA and part of ITS1-5.8S-ITS2, respectively, revealing an abundance of isolates with sequence similarity to Klebsiella and Bacillus and Meyerozyma, which have been used as biological control agents and their ability to promote plant growth has been demonstrated. We have shown that microorganisms from borer regurgitate inhibit phytopathogen growth in vitro. Still, further investigation of the possible functions of D. saccharalis-associated microorganisms may help understand their ecological role in plant-insect-phytopathogen interaction.
