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

objectiveThe functional polymorphism in the promoter region of the SLC6A4/5-HTT serotonin transporter gene (5-HTTLPR) has been linked to altered stress response. Carriers of the short (s-) allele have increased negative psychological reactions and stress hormone release compared with carriers of the long (l-) allele, interacting with severe life events including childhood trauma. High stress levels are associated with cognitive impairments in a variety of clinical and experimental studies. Patients with psychotic disorders are characterized both by more childhood traumatic events and abnormal stress responses and by significant but highly variable cognitive dysfunction. We hypothesize that 5-HTTLPR variations and long-term effects of childhood trauma interact and contribute to some of the variation in cognitive dysfunction seen in patients with psychotic disorders.

methodsPatients with psychotic disorders (schizophrenia and affective spectrums) were recruited from a catchment area-based treatment organization. History of childhood abuse was obtained by the Childhood Trauma Questionnaire. Cognitive function was assessed through a comprehensive, standardized neuropsychological test battery. 5-HTTLPR genotypes were analyzed using standard polymerase chain reaction.

resultsWe observed a significant interaction between 5-HTTLPR variants and childhood trauma across cognitive domains; here, homozygotic s-carriers exposed to high levels of childhood trauma (physical neglect and abuse) had significantly poorer cognitive functioning than all other groups.

conclusionsOur results need replication but underline the importance of investigating childhood trauma and its interaction with genetic markers when studying cognitive dysfunction in patients with psychotic disorders.
