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
purposeDigital 3D exoscopes are promising tools for microneurosurgery. The results of exoscope-assisted resection of intracranial meningiomas have only been addressed in few case reports. We retrospectively compared the results of exoscope and microscope-assisted surgery of falx and parasagittal meningiomas.
methodsWe included all consecutive adult patients (n = 36) with falx or parasagittal meningioma who were operated with curative intention during an 8-year period by one senior neurosurgeon. The operations were performed either with a surgical microscope (n = 16; Zeiss Kinevo or Pentero 900) or a digital 3D exoscope (n = 20, Aesculap Aeos). We reviewed the pre- and postoperative radiological images, clinical examinations and surgical reports to assess clinical outcomes and complications. We also analyzed surgical videos.
resultsGross-total resection (Simpson grade I-II) was achieved in approximately 90% of the patients in both groups (89% in exoscope and 92% in microscope group). The duration of the operation was slightly longer (117 vs. 88 min) in the exoscope group. Surgical outcomes were comparable, despite there being larger tumors (median diameter 53 vs. 38 mm) with higher grades (WHO Grade 2-3: 45% vs. 19%) in the exoscope group. Transient postoperative complications were more frequent in the exoscope group (40 vs. 25%) mainly related to the larger tumor size.
conclusionThe digital 3D exoscope is an effective tool for performing surgery on falx and parasagittal meningiomas. The extent of removal, clinical results and complications seem to be comparable to surgical microscope even in large tumors. Larger prospective studies are required to confirm this result.
