Spontaneous improvement of secondary empty sella syndrome due to re-expansion of an intrasellar cyst: A case report.
Article in Surgical neurology international, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundIn patients with secondary empty sella syndrome (ESS), optic nerve herniation into the sella turcica is caused by shrinkage of the mass lesion at the sella turcica, resulting in visual disturbance. ESS is often surgically treated using chiasmapexy. Here, we report the first case of spontaneous improvement in a patient with ESS. CASE DESCRIPTION: A 69-year-old woman presented with a month-long history of visual disturbance in the right eye, poor visual acuity, and quadrantanopia in her upper temporal visual field. Magnetic resonance (MR) imaging showed herniation of her right optic nerve and gyrus rectus into the sella turcica. The visual disturbance gradually improved, and the patient's vision became almost normal after a month without any treatment. On repeated MR imaging, it was observed that the herniation of the right optic nerve and gyrus rectus disappeared due to an intrasellar cyst re-expansion. The secondary ESS caused by the shrinkage of the intrasellar cyst resulted in the visual disturbance and re-expansion of the cyst resulted in spontaneous improvement of symptoms. The visual disturbance did not recur for a year.
conclusionPatients with secondary ESS without severe symptoms may be followed up conservatively. However, surgical treatment should be applied if symptoms deteriorate or do not improve.
