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

objectiveSchizophrenia has been associated with age-related abnormalities, including abnormal glucose tolerance, increased pulse pressure, increased inflammation, abnormal stem cell signaling, and shorter telomere length. These metabolic abnormalities and other findings suggest that schizophrenia and related disorders might be associated with accelerated aging. Testosterone activity has a progressive decline with increasing age.

methodsWe tested the hypothesis that circulating biologically active testosterone is lower in newly diagnosed, antipsychotic-naive male patients with nonaffective psychosis than in matched control subjects.

resultsPatients (n = 33) were matched to control subjects (n = 33) for age, sex, body mass index, socioeconomic status of the family of origin, and smoking. The free androgen index, a measure of biologically active testosterone, was significantly lower in the psychosis group (mean [standard deviation] = 57.7% [26.1]) than in control subjects (71.6% [27.0], p = .04), with an effect size of 0.53. Multivariate analysis also supported the findings. In the psychosis group, free androgen index had a significant negative correlation with the conceptual disorganization item (r = -0.35, p = .049) but not with reality distortion (r = -0.21, p = .24), negative symptoms (r = 0.004, p = .98), or depression (r = -0.014, p = .94).

conclusionsLower testosterone level is consistent with accelerated aging in nonaffective psychosis, but further testing of this hypothesis is needed.
