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

objectiveWe aim to test the feasibility of applying Optical Coherence Tomography (OCT), a non-destructive, non-contact, real-time imaging technique to investigate the internal changes within leaves under sound stimulation.

resultsApplication of a spectral-domain OCT operating at 836.1 nm revealed that depth-resolved images obtained under no sound and under the application of sound stimuli of 100 Hz and 10 kHz sound at 100dB sound pressure to arugula (Eruca sativa) for a minute revealed a clear frequency dependence. The ratio of the OCT structural x-z images of a month-old arugula seedlings was obtained before and after the application of sound. From the ratio images, it was found that the effects under low and high-frequency sounds differed. The low-frequency sound of 100 Hz showed increased activity within the leaf compared to a high frequency of 10 kHz. Our results demonstrate that OCT can potentially investigate the effects of sound in plants speedily and thus has implications in agriculture applications.
