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

Transcranial photobiomodulation is an innovative method for the stimulation of neural activity which consists of the exposure of neural tissue to low-level light irradiance. In the present study, light-emitting diodes (LEDs) were used as light source due to their practicality and low cost. The objective was to analyze the effects of transcranial photobiomodulation using 945-nm LED in university students with anxiety and depression. Sample was composed of 22 individuals (17-25 years of age) divided into 2 groups of 11. LED group was treated with 945-nm LEDs for 1 min and 25 s (9.35 J/cm
