Effects of Capsaicin on the Growth, Development, and Nutritional Profiles of Black Soldier Flies Fed a High-Fat Diet.
Article in Insects, 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
This study evaluated the effects of capsaicin on the growth and development and the nutritional composition of black soldier fly larvae (BSFL) under high-fat substrate conditions. The results showed that, under a high-fat background, low levels of capsaicin (0.01-0.05%) had a relatively small adverse effect on the growth of larvae, while 0.1-0.2% treatment led to a decrease in the accumulation of larval weight. The pupation age did not show a monotonous change consistent with the addition amount of capsaicin. The conversion efficiency of digested feed in the high-fat control group was lower than that in the basal diet control group. It slightly increased with 0.01-0.05% capsaicin treatment and decreased again with 0.2% treatment. The amino acid composition of the insect body is relatively stable overall, but the contents of glutamic acid, tyrosine, etc., decrease under high doses of capsaicin. The changes in fatty acid composition are more sensitive, mainly manifested as fluctuations in the ratios of C12:0, C18:1n-9, and C18:2n-6. The results indicate that black soldier flies have a certain tolerance to spicy and high-fat substrates, but when the addition of capsaicin increases, their growth and nutrient deposition will be adversely affected.
