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
purposeThe primary aim of this study was to assess clinical and surgical safety for patients who underwent transition surgery from a percutaneous to an active transcutaneous bone conduction implant. A secondary aim was to report audiological changes and outcomes for quality of life post the transition surgery.
methodsAn observational, descriptive and prospective study was performed in a tertiary referral center. Patients who underwent transition surgery as part of their treatment were included. Clinical and surgical safety were assessed through intraoperative and postoperative complications and adverse events. The audiological outcomes were assessed with the Hearing in Noise Test, both fixed noise and adaptative noise measurements. Quality of life changes were evaluated using the Glasgow Benefit Inventory, postoperatively.
resultsThe study of 23 cases (18 patients) found minor complications in 5.3% (6/113 follow-up points) and no major complications. Audiometric results showed no significant differences in speech understanding (fixed noise=-0.011%, p = 0.99; adaptive noise = 0.236dB, p = 0.617). Quality of life scores increased moderately (+ 27.0 ± 33.9), with notable gains in general health (+ 29.9) and social support (+ 31.8), and a modest improvement in physical well-being (+ 10.6).
conclusionsThe study showed that transitioning from a passive percutaneous to an active transcutaneous bone conduction implant is safe, with no major adverse events and only a few minor complications. The audiological outcomes with transcutaneous implants were maintained with respect to percutaneous implants, while quality of life improvements were notable in general health and social support. Clinicians should use these insights to guide patient discussions and tailor post-operative care.
