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

Current trend of pursuing higher resolution in uncooled cost-effective infrared imagers demands thermopile sensing units with higher responsivity. Conventional designs often have limitations such as non-uniform temperature distribution among individual thermocouple legs or complex fabrication process, which limit further responsivity improvement. Here, a novel thermopile featuring a radially-distributed spiral structure with bilayer P-poly/Al thermocouples is proposed. The radially distributed legs along with the circular membrane effectively improve the temperature uniformity among individual thermocouples. Meanwhile, the spiral bilayer configuration decreases thermal conductance and increases the thermocouple number simultaneously, resulting in a significant enhancement of the responsivity. The spiral parameter was designed and optimized, and the fabricated sensors were characterized and compared with conventional non-spiral thermopiles. Experimental results demonstrate a responsivity of 52.53 V/W and a specific detectivity of 9.76 × 10
