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 objective of this study is to describe the detailed surgical anatomy of the infracochlear approach to prevent complications and to compare the postauricular transcanal microscopic and endoscopic approaches to reach the petrous apex.
methodsCadaver heads were dissected using a binocular surgical microscope, endoscopes, and an electric drill. The dimensions of the access field that could be reached and manipulated with surgical instruments and straight drill via postauricular transcanal microscopic and endoscopic approaches were evaluated.
resultsBoth postauricular microscopic and transcanal endoscopic approaches were considered to be inapplicable in cases with a tympanic cavity located jugular bulb closer than 3 mm to the cochlea. This relationship was seen in 3 (9%) sides of the cadavers. In 4 specimens (12%), a cochlear aqueduct with an open lumen was detected. Both postauricular microscopic and transcanal endoscopic approaches reached a nearly identic dissection area. Detailed anatomy of the approach and measurements about the topography of the third portion of the facial nerve from the tympanic cavity were presented.
conclusionBoth traditional microscopic postauricular and endoscopic transcanal approaches provided comparable access areas to the inferior petrous apex with wide exposure, and radiologic measurements were compatible. A tympanic cavity located jugular bulb in close relation with cochlea was the only instance that restricted the applicability of this technique.
