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

The conversion of waste materials into value-added functional photocatalysts represents a sustainable strategy for environmental restoration. Metal-organic frameworks (Cu-BDC) synthesized from waste-derived precursors were utilized as templates to construct CuO@ZnO n-n heterojunction photocatalysts. XRD analysis confirmed the growth of wurtzite ZnO and monoclinic CuO phases, as evidenced by selected-area electron diffraction (SAED) patterns showing well-defined diffraction rings, indicating crystallinity. HRTEM revealed lattice spacings of 0.262 nm and 0.232 nm corresponding to ZnO (002) and CuO (111), respectively. DRS-Tauc analysis demonstrated enhanced visible-light absorption and a narrowing of the bandgap from 3.1 to 2.89 eV upon CuO incorporation. CuO
