Sulfotransferase 4A1 Haplotype 1 (SULT4A1-1) Is Associated With Decreased Hospitalization Events in Antipsychotic-Treated Patients With Schizophrenia.

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
objectiveTo evaluate a common genetic variant, sulfotransferase 4A1 haplotype 1 (SULT4A1-1), as a predictor of hospitalization events due to the exacerbation of schizophrenia for patients treated with antipsychotic medications. Haplotypes were determined using single nucleotide polymorphism data.
methodThe study included 417 white subjects from the Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) study with a DSM-IV diagnosis of schizophrenia. Patients were assigned to 1 of 4 atypical antipsychotics (olanzapine, quetiapine, risperidone, or ziprasidone) or to the first-generation antipsychotic perphenazine. Kaplan-Meier survival analysis and Cox proportional hazards regression models were used to measure if haplotype status impacted hospitalization events for these 5 treatments. Haplotype status was evaluated for its relationship to hospitalization events regardless of treatment and for the individual treatments, with or without previous exacerbation. Data for the CATIE study were collected from January 2001 to December 2004. The current post hoc analysis was performed between May 2011 and August 2011.
resultsIn phase 1 of the trial, considering only the first hospitalization events, the haplotype had a significant impact on hospitalization events, with a hazard ratio for SULT4A1-1(-) versus SULT4A1-1(+) of 2.54 (P = .048). When prior exacerbation was included in the model for phase 1, the hazard ratio was 2.34 (P = .072) considering only the first hospitalization event and 2.71 (P = .039) considering all hospitalization events in the phase. When data for all phases were evaluated, SULT4A1-1(-) status was associated with increased hospitalization risk for subjects treated with olanzapine, with a hazard ratio of 8.26 (P = .041), and possibly for subjects treated with quetiapine, with a hazard ratio of 6.80 (P = .070).
conclusionsThe SULT4A1-1 haplotype may be an important predictor of risk of hospitalization. SULT4A1-1(+) status was significantly associated with decreased risk of hospitalization when the subjects were treated with olanzapine.
