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: Non-adherence to medication therapy in type 2 diabetes mellitus (DM2) is prevalent. Theoretical models have been used to identify the proximal determinants of behavior. Aim: To identify the direct psychosocial predictors of adherence to insulin therapy based on Theory of Planned Behavior (TPB), among outpatients with DM2. Methods: Longitudinal and predictive study, whose data was collected at baseline and 3-month follow-up. At baseline ( Results: One point in the Intention score led to a mean increase of 12.5% in the proportion of insulin doses, and there was a mean increase of 25% in the probability of the person taking insulin every day or practically every day. Attitude was a predictor of Intention. The moderation analysis demonstrated that higher levels of Perceived Behavioral Control weakened the effect of Attitude on Intention. Conclusions: The results showed that Intention was predictor of behavioral measure of adherence and the proportion of insulin doses. Attitude was predictor of Intention and Perceived Behavioral Control moderated the effect of Attitude and Subjective Norm on Intention. These findings highlight the importance of developing interventions that prioritize motivational strategies to enhance insulin adherence in the clinical practice. However, future studies with larger sample sizes and the inclusion of belief assessments are recommended to optimize the understanding of the psychosocial determinants of insulin adherence among outpatients with DM2.
