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
backgroundA study was made of the clinical periodontal changes and buccal cortical bone modifications using cone-beam computed tomography (CBCT) in anterior maxillary teeth with chronic apical periodontitis one year after periapical surgery with submarginal incision. MATERIAL AND
methodsA prospective case series analysis was made of anterior teeth subjected to apical surgery and submarginal incision with a follow-up period of 12 months. Clinical periodontal parameters were recorded, along with tomographic measurements of the buccal cortical bone and volume of the lesion (in mm3) before and one year after surgery. Success was assessed based on the clinical and tomographic data.
resultsThirty-six anterior maxillary teeth from 36 patients with a mean age 43.1 years were enrolled in the study. One year after surgery, mean gingival recession was found to be 0.19 mm with a clinical attachment loss of 0.28 mm. Marginal bone loss was 0.25 mm. The thickness of the buccal cortical bone decreased at all three measurement points, with the greatest decrease being observed at 3 mm from the bone crest (0.58 mm). The distance from the apex to the buccal cortical bone (depth of the apex) decreased 0.59 mm at one year. The clinical parameters (clinical attachment level and probing depth) were not correlated with the tomographic measurements (cementoenamel junction-bone crest distance). The mean lesion volume was 457 mm3 at baseline versus 28.4 mm3 one year after surgery, representing a decrease of 93.8% in 12 months. The success rate at one year postsurgery was 94.4%.
conclusionsOne year after apical surgery of anterior maxillary teeth with submarginal incision, only minimal clinical periodontal and tomographic changes are observed, with no clinical relevance. The mean lesion volume decreased 93.8%, and the success rate was 94.4%.
