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

Mid-infrared spectroscopy allows precise and label-free molecular fingerprinting of the chemical composition of bacteria. Waveguide spectroscopy promises several benefits compared to conventional ATR-FTIR spectroscopy, such as higher sensitivity and the potential for miniaturization. In this study we demonstrate mid-infrared spectroscopy of lipopolysaccharides and intact bacteria cells on a diamond waveguide with quantum cascade lasers as light source. The diamond waveguide with aluminum nitride as undercladding was tuned with a thin silicon film to specifically target the polysaccharide part of the mid-infrared spectrum (1200-1050 cm
