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
Liquid preservation of boar semen is widely used in artificial insemination programs; however, storage-induced oxidative stress progressively impairs sperm function and reduces fertility potential. The present study evaluated the effects of gold nanoparticles (AuNPs) on sperm quality, functional integrity, and oxidative status of liquid-preserved boar semen during storage at 17 °C. 24 ejaculates collected from four healthy Lumsniang breeding boars were diluted in Beltsville Thawing Solution (BTS) extender and allocated to three treatment groups: T0 (control, no AuNPs), T1 (5 million AuNPs/ml), and T2 (10 million AuNPs/ml). Extended semen samples were stored for 5 days and evaluated on days 0, 3, and 5. Sperm motility and kinematic parameters were assessed using computer-assisted semen analysis (CASA), while viability, plasma membrane integrity, acrosomal integrity, and mitochondrial membrane potential were determined using CFDA/PI staining, hypo-osmotic swelling test, FITC-PNA staining, and JC-1 staining, respectively. Oxidative status was assessed by measuring malondialdehyde (MDA) concentration and total antioxidant capacity (TAC). Storage duration significantly affected all sperm quality parameters (
