Clinical study on the efficacy of LED phototherapy for pain control in an orthodontic procedure.
Trial report in Lasers in medical science, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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.
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
Pain is an unpleasant and emotional subjective sensory experience that occurs during orthodontic procedures. Currently, LED phototherapy is an alternative to the use of laser light as analgesic agent due to similarity of response and lower cost. This case-control, quantitative, qualitative, and longitudinal study aimed to investigate the effect of IR LED phototherapy (λ846 ± 20 nm) in pain during the process of tooth separation during orthodontic treatment. After approval by the Institution Ethics Committee, 40 patients (30 female/10 male, 20-30 years old, average age 24.5 ± 2.6 years old) fulfilling the inclusion criteria entered the study and received a set of four visual analog scales (VAS) for scoring pain immediately, 48 h, 72 h, and 7 days after the insertion of the separating elastics. The patients were randomly distributed into two groups (experimental and control). The patients of experimental group received LED phototherapy (180 mW, 22 s, 4 J, 8 J/cm
