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

Core-needle (tru-cut) biopsy is increasingly used in gynecologic oncology for tissue acquisition and molecular assessment. Adequate operator training is essential, but hands-on opportunities and affordable pelvic simulation models remain limited. This pictorial essay describes a step-by-step approach for pelvic ultrasound-guided core-needle biopsy using a low-cost gelatin-based phantom adapted from a previously published model. The phantom incorporates target lesions and optional simulated bowel loops to increase procedural complexity. The accompanying images and instructional video demonstrate phantom preparation, probe handling, needle-beam alignment, lesion targeting, and simulated biopsy using transvaginal/transrectal and transabdominal approaches. This reproducible, inexpensive model may facilitate simulation-based training and improve familiarity with biopsy equipment and needle-tip visualization before supervised clinical practice.
