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
Objective: The purpose of this study was to introduce a watertight duraplasty with artificial dural grafts for anterior skull base (ASB) reconstruction. Methods: Between November 2019 and October 2023, we used artificial dural grafts for the ASB reconstruction in 10 cases of recurrent benign cranionasal communicating tumors. Through a transcranial subfrontal approach, the tumor was totally removed and the skull base defect was repaired using the NormalGEN and DuraMax artificial dural grafts. Clinical and imaging follow-ups were conducted to screen for the occurrence of postoperative cerebrospinal fluid (CSF) leakage, intracranial infection, and encephalocele. Results: Gross total resection of tumor and ASB reconstruction with the artificial dural grafts were achieved in 10 patients. The patients were followed up clinically for 11 to 52 months (mean 26.0 months) and underwent medical imaging follow-up for 6 to 36 months (mean 18.4 months). One patient presented with CSF leakage on day 47 after the operation. Another patient endured intracranial infection without CSF leakage on the fifth day after the operation. Both patients were cured. No encephalocele was observed during the follow-up period. All the patients achieved a favorable recovery. Conclusion: Following transcranial resection of benign cranionasal communicating tumors, we utilized artificial dural grafts for ASB reconstruction when the frontal pericranium was impaired by tumor invasion or previous surgery. Our initial experience and postoperative follow-up have proven that the method is feasible and reliable in selected cases.
