No indication of histological changes in embryonic somatosensory cortex development upon maternal aspartame consumption in mice.
Article in NPJ science of food, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Non-nutritive sweeteners are widely used in multiple diets and are considered a healthy alternative for pregnant women reducing sugar consumption, thereby preventing maternal obesity and gestational diabetes. While some controversies have been raised regarding their safety for human consumption, particularly aspartame, the effects of aspartame on prenatal brain development have rarely been studied. In this study, we investigated whether maternal aspartame consumption within a physiologically relevant range for normal daily consumption by humans affects neocortical development in mice. Here we show that daily maternal aspartame consumption at 18% of the European Food Safety Authority-approved daily dosage does not significantly alter the structure of the somatosensory cortex, nor the numbers of excitatory neurons, inhibitory neurons, astrocytes, or oligodendrocytes in mouse pups less than 48 hours old. These results suggest that aspartame has no detectable impact on somatosensory cortex development in mice. This study provides additional information that can be utilized by expectant mothers making choices about their diet.
