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

This paper investigates the light-induced thermoelastic spectroscopy (LITES) based on transmitted light amplification to realize high-precision gas detection. The modulated laser beam passes through a multi-pass cell and is then coupled to an optical amplifier. The multi-pass cell reflects the laser beam 100 times, has an optical length of 16 m, and its transmitted light intensity is 1.67 mW. A narrowband fiber optical filter with a bandwidth of 0.8 nm is utilized to suppress optical noise. Based on the transmitted light amplification, the signal-to-noise ratio (SNR) is improved by a factor of 3.6. To investigate the enhancement of second harmonic (2
