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

purposeThis study was conducted to characterize UV imaging as a platform for performing in vitro release studies using Nicorette® nicotine patches as a model drug delivery system.

methodsThe rate of nicotine release from 2 mm diameter patch samples (Nicorette®) into 0.067 M phosphate buffer, pH 7.40, was studied by UV imaging (Actipix SDI300 dissolution imaging system) at 254 nm. The release rates were compared to those obtained using the paddle-over-disk method.

resultsCalibration curves were successfully established which allowed temporally and spatially resolved quantification of nicotine. Release profiles obtained from UV imaging were in qualitative agreement with results from the paddle-over-disk release method.

conclusionVisualization as well as quantification of nicotine concentration gradients was achieved by UV imaging in real time. UV imaging has the potential to become an important technology platform for conducting in vitro drug release studies.
