Patient perspectives in the development and use of long-acting antipsychotics in schizophrenia: focus on olanzapine long-acting injection.

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.
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
Schizophrenia is a chronic mental disorder generally treated with antipsychotic medication. However, non-adherence and partial adherence to antipsychotic medication treatment is common and long-acting injectable "depot" preparations of antipsychotic medications have been used as an alternative to oral medication therapy for patients for whom adherence is a clinically significant problem, as well as for the sake of convenience and in response to patient preference. Olanzapine long-acting injection (OLAI) is a new treatment option and has been approved by several regulatory agencies for the treatment of schizophrenia. OLAI is a crystalline salt formulation of olanzapine and pamoic acid. Efficacy was established in 2 double-blind randomized clinical trials of OLAI for the treatment of acute schizophrenia and for the maintenance of response. The therapeutic OLAI dosages are 150 mg q2 weeks, 210 mg q2 weeks, 300 mg q2 weeks or q4 weeks, and 405 mg q4 weeks, administered by deep intramuscular gluteal injection with a 19-gauge needle. Injection volume ranges from 1 to 2.7 mL. OLAI has essentially the same general tolerability as that of oral olanzapine; however with the depot there is the additional risk of a post-injection delirium sedation syndrome occurring at a rate of 0.07% of injections, requiring a risk management plan that includes observing the patient for 3 hours post injection.
