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
Background: A primary goal for a mature tooth autotransplant is preserving tooth vitality. Platelet-rich fibrin (PRF) has characteristics that may improve the success of autotransplanted mature teeth by decreasing harmful inflammation and boosting vascular growth. This prospective human trial aimed to evaluate the effectiveness of PRF on vitality in a mature tooth replantation model. Methods: This double-blind, randomized controlled trial included 18 participants with 70 single-rooted vital teeth planned for prosthetic extraction. Experimental teeth were extracted and apicoectomized to increase vascular growth. PRF was condensed into the canals before teeth were replanted in their respective sockets. In the same patient, control teeth received identical treatment without PRF. Teeth were splinted and monitored for 3 through 11 months before final vitality testing, extraction, and histologic analysis of pulpal tissue. Results: Comparison of vitality testing did not yield statistically significant differences between experimental and control teeth. In addition, histologic evaluation of infiltrate type and health of pulp did not reveal any benefit from the addition of PRF. Out-of-mouth time marginally differed between experimental and control groups (mean difference, 0.26 [95% CI, -0.50 to -0.020]; Conclusions: PRF applied to the periapical region did not improve the chances of vitality retention after extraction and replantation; however, it is possible site inflammation may have affected vitality results and confounded the effects of PRF.
