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

contextChronic diabetic foot ulcers (DFUs) are associated with the collapse of endogenous bioelectric field gradients and redox-compromised wound microenvironments, conditions under which externally applied electroceutical stimulation and reactive oxygen species (ROS)-dominated photodynamic therapies become ineffective or deleterious. This limitation motivates the search for intrinsic, bias-free mechanisms capable of generating localized bioelectric-scale fields using benign external energy inputs. At photoactive organic-semiconductor interfaces, excited-state intramolecular proton transfer (ESIPT) offers a pathway by which molecular photophysics may be converted into interfacial electrostatic modulation, yet this transduction mechanism has not been formulated within a rigorous quantum-electrostatic framework.

methodHere, we develop a first-principles quantum modeling framework establishing the Stokes-Induced Stark Effect (SISE) at quercetin-ZnO interfaces as a bias-free mechanism for interfacial electric field generation. Visible-light excitation of chemisorbed quercetin induces ultrafast ESIPT-driven Stokes relaxation, accompanied by excited-state dipole reconfiguration (Δµ ≈ 5-15 D, τ ≈ 100 fs). This time-dependent dipole couples electrostatically to ZnO surface states, generating localized interfacial Stark fields of order 10
