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

Atlanto-occipital assimilation is extremely rare congenital anomaly, characterized by partial or complete fusion of atlas and occipital bone leading to altered cranio-cervical junction anatomy. In our patient, basilar invagination resulted in acute angulation and narrowing of foramen magnum. Crowding of structures at foramen magnum was seen with tonsillar herniation and compression of brain stem. Edema signal in proximal cervical cord was also seen. Bilateral atlanto-occipital assimilation with increased atlas to dens distance seen suggestive of atlanto-axial instability. Overall findings were suggestive of Chiari I malformation with atlanto-occipital assimilation.
