Tunable Drug Release Rate Using Modular Oral Dosage Forms.
Article in Pharmaceutics, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Oral dosage forms with adjustable drug release profiles were prepared using progesterone (PGR) as a poorly-soluble model drug. The dosage forms were made as stack assemblies of functional modules. The modules were made as PGR-carrying HPMC films cut into wafer-like circular pieces. Two types of modules were used in the study; one exhibited comparatively fast drug release and the other slow release. The fast vs. slow release of each type of film utilized resulted from the grade of HPMC used in each case. Drug loading in the assembly was controlled through the total number of modules. By adjusting the proportions of the two types of modules, it is possible to fine-tune the drug release rate of the multi-layer assemblies to a wide range of profiles, bracketed between a high and low end, corresponding to the inherently fastest or slowest release obtainable with the specific materials and procedures employed. This procedure is suitable for adjusting the spring-and-parachute parameters for enhancing/optimizing the bioavailability of poorly-soluble drugs, and for developing patient-centric formulations.
