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

The phospholipids in the neuronal membranes of the brain are rich in highly unsaturated essential fatty acids (EFAs). It has been hypothesised that abnormalities of phospholipid metabolism are present in patients with schizophrenia and that the EFAs omega-3 polyunsaturated fatty acids, and eicosapentaenoic acid (EPA) in particular, may have a role in treating this illness. Considerable preclinical and clinical evidence provides support for this proposal. An epidemiological study reported a better outcome for patients with schizophrenia in countries where the diet is rich in unsaturated fatty acids. Evidence of abnormalities of EFAs has been found in erythrocyte membranes and cultured skin fibroblasts of patients with schizophrenia, and abnormal retinal function and niacin skin flush tests (markers of omega-3 polyunsaturated fatty acid depletion) have also been reported. Case reports and an open-label clinical trial reported efficacy for EPA in schizophrenia. Four randomised, controlled trials of EPA versus placebo as supplemental medication have now been reported. Two of these trials showed significant benefit with EPA on the positive and negative symptom scale total scores, whereas the other two did not show any effects on this primary efficacy measure. One study also reported a beneficial effect on dyskinesia. In the only published trial in which EPA was used as monotherapy versus placebo in schizophrenia, some evidence was found to suggest antipsychotic activity. Taken together, there is considerable evidence to suggest abnormalities of EFAs in cell membranes of patients with schizophrenia, and there is preliminary evidence that EPA is an effective adjunct to antipsychotics.
