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
purposeOn the day of fresh oocyte retrieval in in vitro fertilization (IVF) cycles, a novel portable artificial intelligence optical microscope (AIOM) was employed to assist in the assessment of semen parameters. This study analyzed the correlation between sperm kinetic and morphological parameters with short-term IVF outcomes. Additionally, it explored whether these parameters could serve as predictive indicators for rescue intracytoplasmic sperm injection (R-ICSI) in IVF patients.
methodsA retrospective analysis was conducted on patients undergoing short-term IVF at the West China Second Hospital of Sichuan University between May 2021 and May 2024. Based on fertilization outcomes, the short-term IVF patients were categorized into a successful fertilization group (group A, n = 281) and a group requiring R-ICSI after failed fertilization (group B, n = 49). AIOM was utilized to analyze semen parameters including pH, sperm concentration, sperm motility parameters, sperm movement trajectory parameters, and sperm morphological parameters. The study further investigated the correlation between these short-term IVF fertilization-related laboratory indicators and IVF outcomes.
resultsNo statistically significant difference was observed in semen pH between the two groups. However, there were significant differences in sperm concentration and the majority of motility parameters. Specifically, compared to group A, patients in group B exhibited lower sperm concentration (p = 0.01), motility (p = 0.01), local motility (p = 0.01), progressive motility (PR) (p = 0.00), total motility (p = 0.01), and amplitude of lateral head displacement (ALH) (p < 0.01), along with higher immotility (p = 0.00). No statistically significant differences were found between the two groups in other sperm motility, velocity, or trajectory parameters. Additionally, sperm morphological parameters were also associated with short-term IVF fertilization outcomes. Compared to group A, group B had higher sperm head length mean (p < 0.01), head perimeter mean (p < 0.01), and head area mean (p = 0.01), as well as lower tail length mean (p = 0.01). Multivariate regression analysis of fertilization outcomes indicated that higher immotility (p = 0.01) and head length mean (p < 0.01), along with lower tail length mean (p = 0.04), were independent risk factors affecting successful short-term IVF fertilization. Notably, head length mean showed a significant negative correlation with polyspermy rate (p < 0.01), whereas tail length mean was significantly positively correlated with polyspermy rate (p < 0.01).
conclusionOptimization of semen parameters with AIOM at the time of fertilization is significantly associated with short-term IVF fertilization outcomes. Abnormal semen parameters at fertilization-specifically, higher immotility and head length mean, along with lower tail length mean-can be considered risk factors for fertilization failure and may serve as predictive indicators for potential R-ICSI.
