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
introductionP-glycoprotein, an ATP-dependent efflux transporter, plays a crucial role in eliminating cellular toxins and affects the intracellular concentration and bioavailability of CDK 4/6 inhibitors. Moreover, dietary flavonoids are natural bio-enhancers that can effectively inhibit the efflux function of these transporters. Therefore, this study aimed to assess the impact of dietary polyphenols on the inhibition of P-glycoprotein and the subsequent efflux of CDK inhibitors palbociclib and ribociclib.
methodsA molecular docking approach was implemented to evaluate the binding interaction characteristics of CDK4/6 inhibitors in the presence of dietary polyphenols at the ATP binding site. Furthermore, the stability of the complexes was evaluated in two conformations of P-glycoprotein, followed by an
resultsThe findings demonstrated that the binding of curcumin and quercetin with high affinity (-51.63 and -47.16 Kcal/mol) to ATP binding sites of P-glycoprotein-palbociclib and ribociclib inward conformation complexes resulted in good stability of complex and minimal fluctuation throughout the course of the simulation. It was evident from the everted gut sac ex vivo study that the presence of 100 μM of curcumin resulted in an increase of 1.77 and 4.20-fold in the intestinal transit of palbociclib and ribociclib, respectively.
conclusionThe study emphasizes the significance of curcumin and quercetin as inhibitors of P-glycoprotein, demonstrating their potential to decrease the efflux of palbociclib and ribociclib, consequently contributing to their bioavailability enhancement.
