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

Excellent electromechanical properties of piezoceramic thin films facilitate ultrasonic energy harvesting in bioelectronic systems. However, most piezoceramic thin films are fragile and cannot maintain mechanical integrity under deformation, hindering their application in soft tissue coupling. Here, we report a freestanding hierarchical-porous barium calcium zirconate titanate (BCZT) thin film that combines crack resistance with efficient ultrasonic energy harvesting. The hierarchical-porous structure, fabricated using polyvinylpyrrolidone (PVP) as a porogen, disperses tensile-side stress concentration and suppresses crack initiation, while reducing the acoustic-impedance mismatch with soft tissue and suppressing interfacial ultrasound reflection. The film exhibits reduced permittivity and a high piezoelectric voltage coefficient of g
