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
The prognosis for ovarian cancer is often poor due to late diagnosis. This is because the disease rarely presents with any specific symptoms in the early stage. There is therefore a need to develop a sensitive device for the routine screening of CA 125, the most widely used biomarker for detecting and monitoring ovarian malignancy. Herein, we report the development of a photoelectrochemical (PEC) immunosensor based on a screen-printed carbon electrode (SPCE) modified with a carbon nanodot/cadmium sulphide (CND/CdS) heterostructure for the sensitive detection of CA 125. Using a drop-casting technique and a self-assembly process, the immunosensor was constructed by the successive immobilization of CND, CdS, an
