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

Agarwood oil, often called attar, is a valuable perfume retainer derived from Aquilaria malaccensis. It is obtained through a process of fermentation followed by distillation. The microbes involved in fermentation during agarwood processing have neither been documented nor their role in the process deciphered yet. The present study characterizes the fungi and bacteria engaged in the agarwood fermentation and assesses their colony forming units (CFU) in three categories of agarwood fermentation broth (AFB) collected from three small-scale industries of Hojai, Assam at varying time points. It was interesting to note that grade-A AFB contained the highest CFU count for both bacteria and fungi; the metabolite profile also revealed that the oil obtained from grade-A agarwood comprised of the highest number of compounds. The CFU count increased from 0 to 21 days during fermentation. A total of 105 bacteria and 9 fungi were isolated from 3 different grades of AFB. Shannon index (H' = 0.81) was observed maximum in grade-C AFB and fisher index (α = 2.6) observed maximum for grade-A AFB. The genus Bacillus with a Pi value of 0.61 exhibited dominance among isolated bacteria, while the genus Galactomyces was dominant among fungi with a Pi value of 0.43. The metabolite profiles of three grades of oil obtained after fermentation and one solvent extracted (S.E.) grade agarwood oil analyzed using GC-MS, which showed distinct differences among the oil. The outcomes of this study are expected to create new opportunities for improving oil production methods by modulating biochemical processes involved in fermentation.
