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

Depressive symptoms abound in schizophrenia and even in subclinical states of the disorder. We studied the frequency of these symptoms and their relationship to negative symptoms from the first psychotic episode on over a long-term course of 134 months on data for 107 patients in our ABC Schizophrenia Study. Prevalence rates of 90 % for presenting at least one negative symptom and of 60 % for presenting at least one depressive symptom in the first psychotic episode illustrate the frequency of these syndromes. After the remission of psychosis the rates fell to 50 % (negative symptoms) and 40 % (depressive symptoms) over a period of 5 years, remaining stable thereafter. After we broke the negative syndrome down into (SANS) subsyndromes, a positive association emerged between anhedonia and depressive symptoms and remained stable over the entire period studied. In contrast, the association between abulia and depression grew increasingly pronounced over the illness course. However, a more detailed look revealed this to be the case in female patients only, whereas male patients showed no such association of these symptom dimensions. We have no explanation at hand for this sex difference yet.
