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

backgroundClozapine (CLZ) stands out for its unique receptor profile, making it more effective than other antipsychotics, especially in treatment-resistant schizophrenia (TRS). There is growing evidence supporting its use in schizoaffective disorder (SZD), although diagnostic challenges and drug characteristics have complicated the implementation of specific clinical trials.

aimCompare efficacy and tolerability of CLZ in real-world patients with TRS and SZD.

methodsProspective, pragmatic, three-month, evaluator-blinded clinical trial with two randomised controlled arms (TRS groups) and a third fixed arm (SZD group). The clinical response was assessed by monthly visits during which the Positive and Negative Syndrome Scale (PANSS), Young Mania Rating Scale (YMRS), Montgomery-Asberg Depression Rating Scale (MADRS), Calgary Depression Scale for Schizophrenia (CDSS), Clinical Global Impression (CGI) and Udvalg für Kliniske Undersogelser were administered. One hundred twenty-seven participants (74.8% men, 25.2% women; 84 TRS, 42 SZD; mean age of 38.53) completed the follow-up.

resultsPatients treated with CLZ showed a greater reduction in all the PANSS subscales, MADRS and CDSS. In cases of SZD, there was a significant decrease in positive (

conclusionsCLZ was effective in reducing psychotic and affective symptoms in patients with dual psychosis, with better outcomes in SZD compared with TRS.EudraCT protocol trial:2021-001278-44 (Comparative analysis of the effectiveness of clozapine in resistant schizophrenia and schizoaffective disorder;
