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

aimThis study aimed to examine symptom changes during short-term discontinuation of antipsychotics up to 3 weeks including the placebo washout phase in acute schizophrenia.

methodsThe data from three double-blind, randomized, controlled trials comparing lurasidone versus placebo in patients with acute exacerbation of schizophrenia were analyzed. Symptom severity was assessed using the Positive and Negative Syndrome Scale (PANSS) total and the Clinical Global Impression-Severity scale (CGI-S) scores. The scores before and after the antipsychotic discontinuation phase were compared, and factors associated with score changes were explored.

resultsAmong 2154 patients participating in the trials, 600 who received antipsychotic monotherapy and completed the antipsychotic discontinuation phase were included in the analysis. No patients received clozapine. The mean duration of the discontinuation phase was 5.9 ± 2.5 days. The PANSS total and CGI-S scores significantly changed from 94.0 ± 9.5 to 95.4 ± 10.5 (P < 0.001) and from 4.9 ± 0.6 to 4.9 ± 0.7 (P = 0.041), respectively, during this phase; however, the absolute difference was minimal. The score changes were not associated with the type or dose of prior antipsychotics, or the duration or strategy (abrupt vs gradual) of antipsychotic discontinuation.

conclusionsSymptoms may not worsen to a clinically meaningful degree after short-term discontinuation of non-clozapine antipsychotics up to 3 weeks in patients with acute exacerbation of schizophrenia, suggesting that antipsychotic efficacy persists at least several days after discontinuation. This finding supports once-daily dosing regimen of antipsychotics and abrupt antipsychotic discontinuation when switching to another antipsychotic.
