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

aimTo determine major sources of microbially produced geosmin in the commercially important aquaculture fish species tilapia. METHODS AND

resultsAbundance and composition of geosmin-producing bacteria in water and fish biosphere (intestine, digesta, and fins) of Nile tilapia (

conclusionThe high abundance of geosmin-producing bacteria in the intestinal mucous layer and digesta may indicate that the digestive system in fish is an important, but hitherto overlooked, source of geosmin and likely other off-flavors in fish. SIGNIFICANCE AND IMPACT OF STUDY: Tainting of fish by microbially produced off-flavors spoils fish quality and lowers consumer preferences for aquaculture-produced freshwater fish. Our results highlight the potential for the application of probiotic microorganisms for management of the intestinal microflora to improve the fish quality. HIGHLIGHTS: -Off-flavor producing bacteria are widely abundant in aquaculture.-Off-flavor producers found on skin surface of fish.-Off-flavor producing bacteria accumulate in the digestive system.-Off-flavor producers might release significant amounts of off-flavor during lysis in the gut.-Off-flavor uptake through the digestive system might be quantitatively significant.
