1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study sought to analyze the correlational relationships between mastoid air cells, the area of the facial recess entrance, and the location of the vertical segment of the facial nerve.

methodsCT scans of 60 ears from 30 patients were analysed. We used MIMICS to obtain inner ear coordinates in CT images. Mastoid air cells were analysed using CT value thresholds to classify them into three groups based on volume: Group A (< 5 mL), Group B (5-8 mL), and Group C (> 8 mL). The coordinates of the inner ear structures were entered into MATLAB to calculate the area of the entrance to the facial recess and the distance from the vertical segment of the facial nerve to the standard coronal and median sagittal planes.

resultsNo significant differences in mastoid air cells volume between gender or side; the entrance area of the facial recess did not differ significantly among Groups A, B, and C; there was no significant relationship between the midpoint of the vertical segment of the facial nerve and the median sagittal plane (P > 0.05). However, the distance from the posterior point of the annulus to the midpoint pyramidal segment of the facial nerve and the distance between the midpoint of the vertical segment of the facial nerve and the standard coronal plane decreased progressively in Groups A, B, and C (P < 0.05).

conclusionThe analyses showed no link between mastoid air cells volume and gender, side, or area of the facial recess entrance. Better mastoid pneumatisation correlates with a closer proximity of the annulus to the facial nerve and a more anterior position of the vertical segment of the facial nerve.
