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

An electrochemical immunosensor based on multiwalled carbon nanotube/zinc oxide nanoparticle (MWCNTs/ZnONPs) composites was fabricated for the sensitive and selective detection of prostate-specific antigen (PSA), an established biomarker for early prostate cancer diagnosis. The MWCNTs/ZnONPs-modified screen-printed carbon electrode (SPCE) provided an enlarged electroactive surface area and enhanced electron transfer kinetics, thereby improving the overall analytical performance. Monoclonal anti-PSA antibodies were covalently immobilized on the composite surface and PSA quantification was conducted using cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Under optimized experimental conditions, the biosensor exhibited a linear response toward PSA concentrations ranging from 5 to 200 ng mL⁻¹, with a detection limit of 5 ng mL⁻¹ (
