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

Optical coherence elastography (OCE) is a non-invasive imaging technique for quantifying tissue stiffness. The spatial resolution of elastography maps is closely related to the spatial sampling density required to adequately represent mechanical features. In this study, we investigated the effect of spatial sampling density on OCE by varying the number of effective sampling points along scanning axes using the proposed phase-gradient velocity estimation method. These methods were validated using agar phantoms and in vivo human facial acne and the results showed that down sampling reduced computational cost by around 69% and up to about 89%. For the down sampling results of the acne dataset, the velocity changed by only 5.82% in an affected lesion. These results provide a practical criterion for reducing acquisition and post-processing time while establishing the quantitative relationship between spatial sampling, elastography accuracy and computational efficiency.
