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

purposeThe introduction of curcumin into clinics is hindered by its low water solubility and poor bioavailability. To overcome these limitations, we developed curcumin implants using poly (ε-caprolactone) as the polymeric matrix.

methodsImplants were prepared by melt-extrusion method; in vitro drug release was optimized for effects of polymer composition, drug load, surface area and water-soluble additives. Implants were also tested under in vivo conditions for cumulative curcumin release, and liver concentration was correlated with its efficacy to modulate selected xenobiotic-metabolizing enzymes (CYP1A1 and GSTM).

resultsDrug release from implants followed biphasic release pattern with Higuchi kinetics and was proportional to the surface area of implants. Drug release increased proportionately from 2 to 10% (w/w) drug load, and incorporation of 10% (w/w) of water-soluble additives (F-68, PEG 8000 and cyclodextrin) did not significantly alter the drug release. In vivo drug release was found to be ~1.8 times higher than in vitro release. Curcumin was detected at 60 ± 20 ng/g in the liver after four days of implantation and was almost constant (8-15 ng/g) for up to 35 days. This time-dependent drop in curcumin level was found to be due to induction of CYP1A1 and GSTM (μ) enzymes which led to increased metabolism of curcumin.

conclusionOur data showed that these implants were able to release curcumin for long duration and to modulate liver phase I and phase II enzymes, demonstrating curcumin's biological efficacy delivered via this delivery system.
