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.

Abstract

objectivesThe aim of this study was to compare patients' preference for olanzapine orodispersible tablet (ODT) with oral conventional tablet (OCT).

methodsA 12-week randomized, crossover, multinational, open-label study was conducted to estimate the proportion of patients preferring ODT or OCT. Outpatients with stable schizophrenia on OCT monotherapy were randomly assigned 1:1 to ODT or OCT. Compliance and drug attitude were measured using the Drug Attitude Inventory (DAI-10) and Medication Adherence Form (MAF) scales; tolerability and safety by Association for Methodology and Documentation in Psychiatry (AMDP-5) questionnaire and adverse event summary.

resultsA total of 175 patients answered a preference question: 106 (61%) preferred ODT and 48 (27%) preferred OCT (P<0.001 adjusted for treatment sequence); 21 (12%) expressed no preference. There was no significant change in DAI-10 with either formulation. MAF was above 75% in 94% vs. 93% of patients on ODC and OCT, respectively. Compliance as measured by tablet count was above 98% on both formulations. The adverse event profiles did not differ between formulations. Mean weight increase over 6 weeks on ODT was 0.8 kg and on OCT was 0.6 kg.

conclusionsGiven the importance of patients' preference for treatment planning and success, the ODT formulation should be routinely considered as a treatment option.
