Artificial oocyte activation may improve embryo quality in older patients with diminished ovarian reserve undergoing IVF-ICSI cycles.

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
backgroundArtificial oocyte activation (AOA) is used to improve fertilization rate following fertilization failure after intracytoplasmic sperm injection (ICSI). Several studies have also shown that AOA may be involved in embryo development. Women with poor ovarian response are more likely to encounter in vitro fertilization (IVF) failure due to poor embryo quality. The aim of this study was to investigate whether AOA could improve embryo quality in older patients with diminished ovarian reserve undergoing IVF-ICSI cycles.
methodsThe retrospective cohort study consisted of 308 patients who fulfilled the POSEIDON Group 4 criteria and received IVF-ICSI cycles. The study group included 91 patients receiving AOA with calcium ionophores following ICSI. A total of 168 patients in the control group underwent ICSI without AOA. The baseline and cycle characteristics and embryo quality were compared between the two groups.
resultsAt baseline, there were more IVF attempts, greater primary infertility, higher basal FSH levels and lower anti-Müllerian hormone (AMH) levels in the AOA group than in the non-AOA group. In terms of embryo quality, there were higher cleavage rates and top-quality Day 3 embryo (TQE) rates, as well as higher percentages of more than 1 TQE and TQE rates ≥50 in the AOA group than in the non-AOA group. The multivariate analysis revealed that AOA was positively associated with more than 1 TQE (adjusted OR 3.24, 95% CI 1.63-6.45, P = 0.001) and a TQE rate ≥ 50 (adjusted OR 2.14, 95% CI 1.20-3.80, P = 0.010). When the study population was divided into 2 subgroups based on the age of 40 years old, the beneficial effects of AOA on embryo quality were only observed in the subgroup of age ≥ 40 years old.
conclusionsOur data suggest that AOA with calcium ionophores may improve embryo quality in older patients with diminished ovarian reserve undergoing IVF-ICSI cycles, especially in women aged ≥40 years.
