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

objectivePrevious anatomic studies have established a reduction in hippocampal volume in schizophrenia, but few have investigated the progressive course of these changes and whether they are trait markers. In the present study, the authors examined hippocampal volumes in relation to age for patients with childhood-onset schizophrenia, their nonpsychotic healthy siblings, and healthy comparison subjects.

methodAnatomic brain magnetic resonance scans were obtained in childhood-onset schizophrenia probands (N=89, 198 scans), their nonpsychotic full siblings (N=78, 172 scans), and matched healthy comparison subjects (N=79, 198 scans) between the ages of 10 and 29 years. Total, left, and right hippocampal volumes were measured using FreeSurfer software and analyzed using a linear mixed-model regression covarying for sex and intracranial volume.

resultsChildhood-onset schizophrenia probands had a fixed reduction in hippocampal volumes (total, left, and right) relative to both nonpsychotic siblings and healthy comparison subjects, whereas there were no significant volumetric or trajectory differences between nonpsychotic siblings and healthy comparison subjects.

conclusionsFixed hippocampal volume loss seen in childhood-onset schizophrenia, which is not shared by healthy siblings, appears to be related to the illness. Decreased hippocampal volume is not strongly genetically related but represents an important intermediate disease phenotype.
