How to optimize culture media osmolality during Assisted Reproductive Technologies treatments.
Observational study in JBRA assisted reproduction, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
objectiveThe objective of our study was to compare the osmolality in sequential and single step culture media, used for in vitro human embryo culture, covered with mineral oil and paraffin, in dry and humid incubators.
methodsWe performed a prospective observational study. A total of 120 Petri dishes, with 960 droplets of culture media, were evaluated. Each dish was prepared with 4 droplets of single step medium and sequential medium. Sixty dishes were covered with mineral oil and 60 with paraffin oil. Half were incubated in a dry incubator and half in a humid. Osmolality was measured on days 1, 3, 5, 7. ANOVA test was performed for statistical analysis.
resultsOsmolality results for single step and sequential medium, that were covered with both mineral and paraffin oil and placed in the dry incubator, significantly increased throughout the study time (D7>D5>D3). In the humid incubator, the results were similar for all periods. Osmolality was significantly lower in humid incubator, in all periods, when droplets were covered with both oils. When both culture media were placed in the humid incubator, no variation was detected, using both oils. However, when single step medium was placed in the dry incubator, covered with mineral oil, we observed a higher osmolality than the covered with paraffin oil.
conclusionsTWe can conclude that humid incubator is better for maintaining osmolality and paraffin oil protect single step media from evaporation in dry incubator.
