The effect of curcumin on serum copper, zinc, and zinc/copper ratio in patients with β-thalassemia intermedia: a randomized double-blind clinical trial.

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
Thalassemia intermedia is a subgroup of β-thalassemia which originates from mutations in the beta-globin gene. Zinc and copper play important roles in the metabolism. Due to its significant therapeutic effects, curcumin has led many studies to focus on curcumin. In a double-blind clinical trial study, 30 patients with beta-thalassemia intermedia with an age range of 20 to 35 years were randomly selected 1:1 to receive either curcumin or placebo for 3 months. Before and after the intervention period, 5 ml of blood was taken to determine the serum levels of zinc and copper. The laboratory tests were checked at baseline and at the end of the treatment. While the serum levels of zinc and zinc/copper significantly increased, the serum levels of copper decreased after 3 months of curcumin intake. In addition, on the basis of baseline characteristics, a negative correlation was found between zinc and body mass index and positive correlations were identified between copper with triglyceride and high-density lipoprotein. Also, the level of ferritin protein in the curcumin group compared to the placebo group showed a significant decrease after 3 months of curcumin use. Therefore, it could be concluded that curcumin might exert a net protective effect on copper toxicity in thalassemia intermedia patients. The investigation also implicated that curcumin represents an approach to regulating zinc homeostasis and may be useful as a complementary treatment of patients with thalassemia intermedia, especially in patients with zinc deficiency or low serum zinc/copper ratio.
