Frozen advanced platelet-rich fibrin as an adjunct to the modified tunnel technique for root coverage: A pilot randomised clinical trial.

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: Platelet-rich fibrin (PRF) is a widely used second-generation blood concentrate in periodontal regeneration. It has a few disadvantages, such as the fragile nature of the membrane, difficulty in suturing, and unpredictability of outcomes. The present study aims to evaluate the clinical outcomes, healing, and postoperative morbidity following the use of frozen advanced PRF (-20°C for 24 h) with modified coronally advanced tunnel (MCAT) technique in the treatment of multiple adjacent recession defects (MARDs). Materials and Methods: This is a prospective, split-mouth, randomized controlled clinical trial including 42 teeth with bilateral MARD in 10 participants. Sites were randomized to frozen (Fz-PRF) and fresh advanced PRF (A-PRF) groups and treated with Fz-PRF using MCAT and A-PRF using MCAT, respectively. Root coverage parameters (recession depth [RD], recession width [RW], complete root coverage, percentage root coverage [%RC], mechanical characteristics [needle passage ease, surgical handling of the membrane, and membrane fraying], postoperative healing [Wachtel's Healing Index], and patient-reported outcomes [discomfort and esthetic satisfaction]) were assessed. Results: Mean %RC ( Conclusions: Fz-PRF showed better root coverage, mechanical properties, and esthetic satisfaction than A-PRF; as a result, it might be an effective alternative to conventional methods of treating gingival recessions.
