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

Background: Antipsychotics are often insufficient for schizophrenia, but the optimal next-step strategies for non-response remain uncertain. Guidelines recommend some pharmacological, psychological, and non-invasive brain stimulation (NIBS) approaches, but we do not know which one works best. We summarized current evidence for schizophrenia non-responsive to antipsychotics. Methods: We searched the Cochrane Schizophrenia Group registry (up till January 13, 2025), and PubMed up till January 8, 2026 for randomized controlled trials (RCTs) of patients non-responsive to prior antipsychotic treatment, with persistent symptoms after at least one adequate 4-week antipsychotic trial. Raters needed to be masked. The primary outcome was change in overall symptoms analyzed using random-effects network meta-analyses of standardized mean differences (SMDs) with 95% confidence intervals (CIs). The protocol was pre-registered (https://osf.io/wcs5d/). Findings: Fifty-nine RCTs (5409 participants; mean age 39.8 years; 3416 men, 1441 women) were included; 5013 contributed to the primary analysis. Antipsychotic combination therapy (k = 18; n = 575; SMD -0.25, 95% CI -0.46 to -0.04; CINeMA: very low) and electroconvulsive therapy (ECT; k = 5; n = 97; SMD -0.51, -0.96 to -0.06; very low) might be more efficacious than continuing the same antipsychotic. Cognitive behavioral therapy for psychosis (CBTp) showed weak evidence of benefit over continuing the same antipsychotic (k = 5; n = 340; SMD -0.23, -0.58 to 0.11; very low). Other strategies-xanomeline-trospium augmentation, dose escalation, transcranial magnetic stimulation, and switching to clozapine or other antipsychotics-were inconclusive. Combination therapy increased adverse events (OR 1.93, 1.26-3.00). We found no evidence of subgroup difference among non-clozapine- and clozapine-non-response. Interpretation: The results were very uncertain. More head-to-head trials are needed. We found no evidence supporting dose-escalation nor switching to clozapine. Very weak evidence suggested efficacy of antipsychotic combination and ECT augmentation and they might be considered, but with substantial caution. Funding: This study was funded by the German Research Foundation (DFG, #468853597) and the Federal Ministry of Research, Technology, and Space (BMTR, #01EE2303B), and partly by a grant from SENSHIN Medical Research Foundation given to YF, DAAD fellowship to NHS and CSC scholarship to YHW.
