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

Freestanding micromachined membranes are often used for thermal isolation in electronic devices such as photon sensors. The degree of thermal isolation plays an important role in determining device performance, and so the ability to suppress the thermal conductance of a membrane without increasing its size or decreasing its mechanical strength is of practical importance. We present a simple method that controllably reduces the thermal conductance of silicon nitride membranes by as much as 56% at temperatures near 100 mK. The thermal conductance suppression is achieved by depositing one additional metal layer patterned into islands or rings onto the membrane surface. Complex impedance and noise measurements of superconducting transition-edge sensors fabricated using this technique show that their noise performance is not degraded.
