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

CYP2D6 has been suggested to be functionally similar to the dopamine transporter. The present study was aimed at analysing the frequency of CYP2D6 alleles and genotype among schizophrenic patients compared to healthy volunteers. CYP2D6 *3, *4, *5, *6, *10 and duplicated alleles were analysed in 128 unselected schizophrenia inpatients (SP) and 142 unrelated white European Spanish healthy volunteers (HV). SP and HV with >2, 2, 1 or 0 CYP2D6 active genes were 4.7, 64.8, 28.1 and 2.3%, and 6.3, 52.1, 33.1 and 8.5%, respectively. The frequency of homozygous for CYP2D6 inactive alleles or poor metabolizers (PMs) was lower (P<0.05) in SP than in HV. Furthermore, the frequency of CYP2D6 inactive alleles was also lower in SP than in HV (16.8 vs 25.7; P<0.05), specifically the CYP2D6*6 allele was not found among patients. The present study shows a lower frequency of PMs in schizophrenic patients than in healthy volunteers supporting the hypothesis of a potential role of CYP2D6 in the vulnerability to schizophrenia.
