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

Focused high-frequency acoustic waves are utilized in industrial non-destructive testing (NDT) on account of their exceptional spatial resolution and high sensitivity. However, the majority of the focusing methods currently adopted for high-frequency transducers are mechanical pressure focusing and lens focusing, which may inflict mechanical damage on piezoelectric elements and give rise to low transmission efficiency. In this paper, an efficient approach to achieving self-focusing at high frequency is proposed. This is accomplished by utilizing half-concave piezoelectric elements. Through the employment of a precise micro-nano processing technology, a self-focusing half-concave ultrasonic transducer operating at a high frequency (62.7 MHz) was designed, fabricated, and characterized. This device exhibits excellent lateral resolution (39 μm) and a - 6 dB bandwidth (76.6%). The outstanding imaging performance was manifested using a multilayer circuit board and a chip. The results imply that the self-focusing half-concave high-frequency ultrasonic transducer has a prospective potential in industrial NDT, especially for defect detection in chip packaging.
