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

To address the therapeutic limitations and metabolic toxicity associated with conventional nanocarriers, a nanostructure using an "MOF-in-MOF" strategy was engineered. The comprises an olsalazine (Olsa)-based copper metal-organic framework (Olsa-MOF) that integrates intrinsic anti-inflammatory properties and enhanced chemodynamic performance. This Olsa-MOF template is integrally enveloped by a tumor microenvironment-responsive TK-based Cu-MOF layer, which demonstrates exceptional photothermal properties. Subsequent surface functionalization with dopamine-grafted hyaluronic acid (DOPA-HA) endows active targeting ability, yielding the final nanocomposite termed Olsa@TK-Cu@HA. Olsa@TK-Cu@HA not only overcomes the limitations of conventional nanocarriers but also offers a novel strategy to enhance the therapeutic efficacy of photothermal therapy (PTT) and chemodynamic therapy (CDT) through targeted modulation of the COX-2/PGE2 inflammatory axis. The Olsa@TK-Cu@HA demonstrates a superior photothermal conversion efficiency (26.8%) and robust reactive oxygen species (ROS) generation, along with pH-responsive release of Olsa. In vitro evaluation demonstrated that Olsa@TK-Cu@HA exerts tumor-selective cytotoxicity, showing 3.5-fold higher potency against cancer cell. Moreover, Olsa@TK-Cu@HA effectively induces immunogenic cell death (ICD), as evidenced by increased extracellular ATP efflux (5.06-fold elevation) and CRT exposure. Concurrently, it downregulates the COX‑2/PGE2 axis to relieve immunosuppression in the tumor microenvironment and suppresses PD‑L1 expression. This coordinated action amplifies ICD‑mediated antitumor immunity, leading to a tumor regression rate of 84.0% in vivo. By integrating precision targeting, stimulus-responsive drug release, and immunometabolic reprogramming, this work moves beyond conventional treatment paradigms and establishes an innovative platform for next‑generation cancer therapy.
