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 study aimed to evaluate the long-term clinical, radiological, and functional results for subtotal petrosectomy and cochlear implant surgery with closure of the external auditory canal and fat obliteration.
methodsWe retrospectively included all consecutive cases of simultaneous subtotal petrosectomy and cochlear implant surgery performed at a tertiary referral center between 2009 and 2016 using the same surgical technique. All patients underwent postoperative high-resolution computed tomography (HRCT) and annual audiological assessments. A 5-year minimum clinical, radiological, and audiological follow-up was performed. The early and late postoperative results were compared. The main outcome measures were complications, postauricular retraction, fat graft reabsorption, and audiological outcomes.
resultsTwenty-nine procedures performed in 23 patients (six bilateral) met the inclusion criteria. The mean age of the patients was 67 ± 13.4 years and mean follow-up duration was 7.5 ± 2 years. At follow-up, postauricular retraction was detected in 24 cases (82.8%), including five cases (17.1%) with subcutaneous protrusion of implant and array. Fat graft volume was significantly reduced at late-HRCT in terms of maximum diameter (2.24 ± 1.0 cm vs 3.69 ± 0.7 cm; p < 0.0005) and surface area (1.88 ± 1.2 vs 4.24 ± 1.6 cm
conclusionsSubtotal petrosectomy with cochlear implantation is an effective long-term technique in selected cases. Fat grafts showed significant reabsorption at long-term follow-up with reaeration of the middle ear spaces. Prolonged clinical and radiological follow-up is recommended for monitoring implant performances and late complications.
