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
backgroundIn the cryopreservation process, rooster spermatozoa are vastly sensitive to reactive oxygen species (ROS). This study aimed to investigate the effects of Lake extender supplemented via Cysteamine (CYS) on the quality and fertility characteristics of rooster semen during the cryopreservation process.
methodsSemen samples were collected from 10 proved Ross-308 roosters, diluted and cryopreserved in the Lake extender which contained 0, 1, 2, 4, and 8 mM of CYS (C-0, C-1, C-2, C-4, and C-8, respectively). Motility parameters, membrane integrity, abnormal morphology, mitochondrial activity, acrosome integrity, viability, apoptosis status, lipid peroxidation, DNA fragmentation, ROS concentration, as well as fertility potential were evaluated after thawing.
resultstotal motility and progressive motility were higher (P ≤ 0.05) in C-1 and C-2 compared to the other groups. The C-1 showed higher (P ≤ 0.05) membrane integrity, mitochondrial activity, acrosome integrity, viability, and lower (P ≤ 0.05) late apoptosis, lipid peroxidation, DNA fragmentation, and ROS concentration compared to the other groups. During fertility evaluation, C-1 presented a higher fertility rate than the control group. In cases of velocity parameters, abnormal morphology, early apoptosis, necrosis, and hatching rate, no significant difference (P > 0.05) was found.
conclusionusing the optimal concentration of CYS (1 mM) in the Lake extender is useful for protecting rooster sperm during the cryopreservation process and it could be used for reproductive programs.
