Effect of CSF shunt on brainstem auditory evoked potential in hydrocephalus secondary to brain tumour.
Article in Acta neurochirurgica, 1991. 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
BAEPs were prospectively studied in thirty patients with hydrocephalus prior to and within 48 hours of CSF diversion. They comprised patients with (1) cerebellar tumours (2) brainstem tumours (3) third ventricular tumours. Preshunt BAEPs were abnormal in 80% patients with cerebellar tumour, 70% patients with third ventricular tumour and in all patients with brainstem tumour. Postshunt BAEPs improved in 70% patients with brainstem tumour and in 40% patients with third ventricular tumours. In both the groups I-III and III-V interpeak latency improved. In group 1, (cerebellar tumours) none of the patients showed improvement in the BAEP after shunt. In 7 patients of this group CCT deteriorated after the shunt. The deterioration was at the III-V interlatency in 5 patients. One patient had deteriorated at both I-III and III-V levels and another had prolongation of the I-III interlatency after shunting. In 6 patients the wave V amplitude reduced by more than 50% after shunting.
