Diet effects on longevity, heat tolerance, lipid peroxidation and mitochondrial membrane potential in Daphnia.
Article in Oecologia, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
The dietary supply of polyunsaturated fatty acids (PUFA) crucially affects animals' performance at different temperatures. However, the underlying physiological mechanisms are still insufficiently understood. Here, we analyzed lifespan and heat tolerance of four genotypes of Daphnia magna reared on either the green alga Scenedesmus obliquus that lacks long-chain (> C18) PUFA, or the heterokont alga Nannochloropsis limnetica that contains C20 PUFA, both either at saturating and near-starvation levels. A significant genotype-by-diet interaction in lifespan was observed at saturating diets. The C20 PUFA-rich diet eliminated differences in lifespan among genotypes on the PUFA-deficient diet. Corrected for body length, acute heat tolerance was higher at low than at high food concentration, at least in the older of the two age groups analyzed. Genotypes differed significantly in heat tolerance, but there were no genotype-by-diet interactions. As predicted, the C20 PUFA-rich diet resulted in higher lipid peroxidation (LPO) and a lower mitochondrial membrane potential (ΔΨ
