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

purposeTo demonstrate 3D volumetric computed tomography (CT) analysis of the internal auditory canal (IAC) in a large pediatric population and to evaluate the relationship between age, sex, and IAC mid-point diameters.

methodsThe study population comprised children between 0 and 16 years of age who underwent temporal bone CT. Five males and five females were included in each age group. The IAC mid-point diameters were measured, and a three-dimensional volumetric reconstruction analysis was made. The receiver operating characteristic (ROC) analysis was performed to detect thresholds for the IAC volumes.

resultsA total of 340 ears were evaluated. IAC volume increases with age, most significantly from ages 0-4 to > 4 years. A moderate and significant monotonic increase in IAC volume with age for both the left and right sides were found (r = 0.37, p < 0.001). A ROC analysis revealed that the optimal threshold for the mean IAC volume was 147 mm

conclusionThe current study provides normative 3D volumetric benchmarks for pediatric IAC development, underscoring its accelerated growth in early childhood and supporting anatomical precision in radiological assessment and otologic surgery.
