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

Transdermal drug delivery systems (TDDSs) were developed for prolonged tamsulosin (TMS) delivery. Double layer (DL) TDDSs were prepared using Eudragit® RL by conventional film-forming. Ethylene-vinyl acetate was used as the backing layer, triethylcitrate as plasticizer, and Capmul® PG-8-70 NF and Captex 170 EP as penetration enhancers (PEs). An increase in either drug or PE concentration caused a significant increase in drug permeation flux. Modulation of drug permeation across Strat-M® membrane was examined using a single layer (SL) having the same thickness and drug content as the DLs, while the DLs were formulated to have variable drug spatial distribution across each layer (DL 4:6 and DL 6:4). SL/TDDS showed significantly higher daily drug permeation than DL/TDDSs for the first 4 days which could be related to the presence of high TMS concentration located on the upper surface of SL/TDDS as a result of solute migration of TMS during the drying process. However, this increase was followed by a progressive linear decrease after 5 days. Deflection points that were characterized by lower drug flux had been shown by SL/TDDS at more than one-point times. In contrast, DL 4:6 and DL 6:4 TDDSs demonstrated an ability to sustain TMS delivery for up to 2 weeks.
