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

introductionRecent advancements in nanomedicine have drawn attention to the use of zinc oxide nanoparticles as apoptotic agents to address triple-negative breast cancer. Halophila beccarii-mediated zinc oxide nanoparticles (Hb-ZnONPs) were fabricated using zinc acetate dihydrate as the precursor.

methodsThe fabricated nanoparticles were characterized based on morphological, structural, and elemental composition using SEM and XRD. The antiproliferative potential of Hb-ZnONPs was studied using the BT-549 cell line as an in vitro model, employing the MTT assay and Annexin V-FITC/PI-based flow cytometry analysis. RESULTS & DISCUSSION: The Hb-ZnONPs exhibited characteristic absorption maxima at 367 nm with a particle size of 35 nm and -44.7 mV stability. XRD confirmed the hexagonal wurtzite structure with an elemental composition of 62.3% Zn and 25.79% Oxygen. The Hb-ZnONPs demonstrated significant cytotoxicity against BT-549 cells, with 35.26% apoptosis at 5 μg/ml and 38.25% apoptosis at 10 μg/ml. However, cells in the late apoptosis stage increased from 14.48% at 5 μg/ml to 28.16% at 10 μg/ml, indicating a nearly twofold increase with the higher concentration.

conclusionHb-ZnONPs may act as promising apoptotic inducers in the chemotherapy of breast cancer.
