A closer look at ping-pong gaze: an observational study and literature review.
Observational study in Journal of neurology, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundLittle is known about ping-pong gaze (PPG) outside of individual case reports. We aimed to describe PPG through an observational study and literature review.
methodsConsecutive patients with PPG at Shanghai General Hospital (SGH) from February 2016 to March 2018 were enrolled. A literature review through March 2018 was conducted.
resultsOf the 14 patients with PPG in SGH, the median age was 60 years and 12 were males. The median Glasgow coma scale score was 7.5. The cycle of the PPG ranged from 1.5 to 6.5 s. The leading three etiologies were acute ischemic stroke in five patients, post-seizure state in three patients, and hypoxic-ischemic encephalopathy in two patients. A total of 88.9% (8/9) of the patients with consistent whole-field PPG had similar bilateral hemispheric damage, whereas 80.0% (4/5) of the patients with PPG in the hemifield had unilateral or extremely asymmetric bilateral hemispheric damage. The hemifiled side was the same side as the sole/dominant hemispheric lesion. The final clinical outcomes were neurologic remission for seven patients, vegetative state for one patient, and death for six patients.
conclusionsPPG is a sign with localizing value that suggests hemispheric damage and asymmetric PPG might help to predict lateralization of the lesions. Acute ischemic stroke is the most common cause of PPG. Etiology and initial outcome are likely important prognostic factors of PPG.
