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
Introduction: During the combined treatment of tumors, the non-interfering transportation of drugs with different solubilities and the controllable sequential release are the main challenges. Here, we reported a double-chamber "Dandelion" -like sequential drug delivery system to realize the sequential release of different drugs for treating malignant tumors synergistically. Methods: After synthesizing mesoporous silica nanoparticles (MSN) by template method, a hydrophilic chemotherapy drug doxorubicin (DOX) was loaded into the channels of mesoporous silica (MSN) and locked with polydopamine (PDA) coating. Next, β-cyclodextrin (β-CDs) was decorated on PDA by Michael addition reaction, and the hydrophobic photosensitizer chlorin e6 (Ce6) was encapsulated into the hydrophobic chambers of β-CDs. Finally, AS1411 was modified on the surface of PDA and obtained DOX@MSN@PDA-β-CD/Ce6-AS1411 nanoparticles (DMPCCA) through which orthogonal loading and effective controlled release of different drugs were realized. Results: Under the sequential irradiations of 808 nm and 660 nm near-infrared (NIR) laser, PDA promoted the extensive release of Ce6 firstly while playing the effect of photothermal therapy (PTT), further to achieve the effect of photodynamic therapy (PDT) of Ce6. Meanwhile, the rapid release of DOX loaded in MSN channels showed a time lag of about 5 h after Ce6 release, through which it maximized the chemotherapeutic effect. Besides, the present drug loading nano-platform combined passive tumor-targeting effect given by EPR and active tumor-targeting effect endowed by AS1411 realized PTT-PDT-chemotherapy triple mode synergistic combination. Conclusion: We offer a general solution to address the key limitations for the delivery and sequential release of different drugs with different solubilities.
