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
objectivesTo compare the pregnancy and neonatal outcomes of
methodsA total of 2300 patients whose spouses have severely low sperm concentration and motility underwent IVT-ET in the Reproduction Medicine Center, Sir Run Run Shaw Hospital from April 2018 to April 2022. After applying the propensity score matching (PSM), 473 fresh embryo transferred cycles and 473 frozen embryo transferred cycles were selected for the study, and the pregnancy and neonatal outcomes were compared between the two groups.
resultsThere were no significant differences in pregnancy outcomes and neonatal outcomes between fresh and frozen embryo groups (all
conclusionsThere were no significant differences in pregnancy and neonatal outcomes between fresh and frozen embryo transfer in spouses of patients with severely low sperm concentration and motility undergoing IVF-ET. Due to the shorter transfer times, less embryo freezing damage and reduced costs, fresh embryo transfer can be considered as the first choice. However, it is not necessary to pursue fresh embryo transfer if maternal oestrogen levels are too high and there is a tendency of overstimulation.
