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
purposeThe purpose of this study is to evaluate the influence of photobiomodulation therapy on the regenerative potential of non-vital mature permanent teeth of healthy Canine dogs.
methods54 mature roots, obtained from 27 premolars, in dogs, were selected and divided into three equal groups where Group I received regenerative endodontic procedures (REPs) using blood clot as a scaffold (positive control), Group II received similar treatment as Group I, followed by photobiomodulation therapy (study group) and Group III did not receive any intervention (negative control). Each group was further divided into three equal subgroups for the evaluation of the vascular area percentage and fibroblast count at 3 different intervals; 3, 10, and 15 weeks. Statistical analysis was performed with R statistical analysis software version 4.1.3
resultsData analysis for vascular area percentages, revealed an insignificant increase in mean values at 3 and 10 weeks for both the positive control and study group, and all values were significantly lower than the negative control (p < 0.001). At 15 weeks, there was an insignificant difference between the study group and the negative control group, with mean values was 9.76 ± 2.25, and 11.97 ± 2.37, respectively. However, both values were significantly higher than the positive control group (2.47 ± 1.0), (p < 0.001). Regarding fibroblast count, there was a gradual increase in mean values recorded at different intervals, reaching its maximum at the 15th week period; they were 41.40 ± 1.14, 56.60 ± 6.11 and 44.67 ± 17.04 for positive control, study group, and negative control respectively, with insignificant differences between the study group and negative control.
conclusionThe results of this study support the revascularization of non-vital mature permanent teeth as an alternative treatment modality. Photobiomodulation could improve the construction of regenerated blood vessels and fibroblasts. However, further studies with longer flow-up periods and different animal models are recommended.
