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

The toxicity of effluents from fires that occur at the wildland-urban interface is a growing concern among first responders, health professionals, and local populations. Benzene ([Formula: see text]) is a key fire emission of particular concern because of its high carcinogenicity. To better understand [Formula: see text] production in harsh fire environments, this paper presents a calibration-free scanned-wavelength interband cascade laser absorption spectrometer for [Formula: see text] that is demonstrated to be robust, portable, and accurate. The spectrometer targets a narrow-band absorption feature located near 2006 cm
