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
Nowadays, the cryopreservation process can produce reactive oxygen species (ROS), which cause damage to the motility, cell membrane, and DNA integrity of sperm. This study is aimed at evaluating the impact of carvacrol, as a powerful antioxidant, on sperm features and improving oxidative stress throughout the cryopreservation procedure. In this prospective study, semen samples from 25 patients with asthenozoospermia were separated into three groups: fresh, freezing, and freezing + carvacrol (a dose of 100 µM). The subsequent parameters were evaluated using standard methods in all three groups: sperm motility according to WHO criteria, sperm morphology using Papanicolaou staining, sperm viability with eosin-nigrosin staining, DNA integrity with acridine orange staining, levels of antioxidant enzymes (catalase, glutathione, and superoxide dismutase), total antioxidant capacity (TAC), and malondialdehyde (MDA) using ELISA. Also, DNA fragmentation was analyzed by the SDFA kit, and mitochondrial membrane potential (MMP) was assessed by rhodamine staining. Average sperm viability, motility, mitochondrial membrane potentiality, integrity of sperm membrane, and antioxidant enzyme levels are meaningfully reduced in the freezing group in contrast to the control group. The freezing group showed a meaningful rise in the mean MDA levels and DNA fragmentation compared to the control group. In the freezing group supplemented with carvacrol, a meaningful rise could be visible in mean percentages of viability, motility, and antioxidant enzyme levels, whereas mean levels of MDA and DNA fragmentation meaningfully declined in contrast to the freezing group. The results demonstrate that carvacrol, a potent antioxidant, offers significant protection against the loss generated by the freeze-thaw procedure, thereby improving sperm quality.
