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

Generic (i.e. non-branded medicine) and therapeutic (i.e. a less expensive drug from the same class) substitution of medication provides considerable financial savings, but may negatively impact on patients. We report secondary qualitative/quantitative analysis of stroke survivors from a pilot randomised controlled brief intervention to increase adherence to medication. Patients' experiences of medication changes were examined in conjunction with electronically-recorded medication adherence. Twenty-eight patients reported frequent medication changes (e.g. size/shape/colour/packaging) and two-thirds of these reported negative effects, resulting in, at least, confusion and, at worst, mistakes in medication-taking. Patients reporting a direct effect on their medication-taking (n = 6) demonstrated poorer objectively-measured adherence (i.e. % doses taken on schedule) than those reporting confusion [mean difference = 19.9, 95% CI (2.0, 37.8)] or no problems [mean difference = 20.6, 95% CI (1.6, 40.0)]. Changes to medication resulting from switching between generic brands can be associated with notable problems, including poorer medication adherence, for a significant minority.
