Effect of high intake of cod or salmon on serum total neopterin concentration: a randomised clinical trial.
Trial report in European journal of nutrition, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02350595 (Fiskespisestudiene 2011-2014. Spiseforsøk Med Fisk. Delstudie 2), which is not on this map. Cited by 3 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.

Abstract
purposePrimarily, to investigate the effect of high intake of cod (lean fish) or salmon (fatty fish) on serum concentration of total neopterin, a marker of cellular immune activation that is associated with cardiovascular disease. Second, to investigate effects of high cod/salmon intake on antioxidant vitamins and elements essential for activity of antioxidant enzymes.
methodsIn this randomised clinical trial, 63 participants with overweight/obesity consumed 750 g/week of either Atlantic cod (N = 22) or Atlantic salmon (N = 22) or were instructed to continue their normal eating habits but avoid fish intake (Control group, N = 19) for 8 weeks. Food intake was recorded, and fasting serum were collected at baseline and endpoint.
resultsSerum total neopterin concentration was reduced in the Cod group (median change - 2.65 (25th, 75th percentiles - 3.68, - 0.45) nmol/l, P = 0.018) but not in the Salmon group (median change 0.00 (25th, 75th percentiles - 4.15, 3.05) nmol/l, P = 0.59) when compared with the Control group after 8 weeks. The estimated daily intake of selenium, iron, magnesium and zinc were similar between all groups. Increased serum concentration of selenium was observed only after cod intake when compared to the Control group (P = 0.017). Changes in serum concentrations of copper, iron, magnesium, all-trans retinol, α-tocopherol and γ-tocopherol were similar between the groups.
conclusionA high intake of cod, but not of salmon, lowered serum total neopterin concentration when compared to the Control group. CLINICAL
