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
Introduction: Tooth color is an important issue for esthetic dentistry professionals and for patients that wish to enhance the appearance of their smiles. At-home whitening under professional supervision is the usual form of treatment for tooth discolorations. The goal of this study was to assess the effectiveness of carbamide peroxide (CP) bleaching through the application of at-home bleaching gel on various dental surfaces. Materials and Methods: Forty coffee-stained premolars were randomly assigned into four groups: only application on the buccal surface (A), only application on the lingual surface (B), application on the buccal and lingual surfaces simultaneously (C), and a control group with no bleaching (D). At-home bleaching gel (Polanight 22%) was used for the procedure. A digital spectrophotometer was used to evaluate bleaching efficacy (color change in CIELAB [ΔE ab] and Whitening Index for Dentistry [ΔWID]). Results: The simultaneous application of CP on buccal and lingual surfaces provides little additional efficiency compared to the buccal application alone, resulting in acceptable bleaching efficacy.
