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
objectiveTo evaluate the efficacy of tunnel technique (TUN) in treatment of teeth with adjacent gingival regression (GR) combined with noncarious cervical lesions (NCCL).
methodsWe collected data from 21 patients (79 teeth) undergoing TUN surgery for GR combined with NCCL. According to GR depth (GRD) and lesion depth (LD) of NCCL, the teeth were divided into group 1 with GRD≤3 mm and LD≤1 mm; group 2 with GRD≤3 mm and LD>1mm; group 3 with GRD>3 mm and LD≤1 mm; and group 4 with GRD>3 mm and LD>1 mm. The mean root coverage (MRC) rate, complete root coverage (CRC) rate, keratinized gingival width, and keratinized gingival thickness were compared among the 4 groups after TUN surgery.
resultsThe keratinized gingival width and thickness were significantly improved after the surgery in the 4 groups. When the GRD was below 3 mm, the MRC was not significantly different between group 1 and group 2 (8.55%
conclusionIn patients with GR combined with NCCL, TUN surgery can obviously improve keratinized gingival width and thickness. GRD has a greater effect on the outcome of root coverage than LD, suggesting that NCCL restoration before TUN surgery may not be necessary. Both GRD and LD should be considered in the evaluation of the clinical efficacy of TUN surgery.
