A Triple-blind randomized controlled trial on the effects of turmeric versus ginger on inflammatory biomarkers in patients with COVID-19.
Trial report in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Inflammation and immune mediators exacerbate COVID-19; turmeric and ginger possess antiviral and anti-inflammatory properties that may mitigate this response. This study compared the effects of turmeric and ginger on inflammatory markers in patients with COVID-19. This triple-blind randomized clinical trial enrolled 144 COVID-19 outpatients at Kowsar Hospital (Semnan, Iran) in 2021. Participants were randomly allocated to group C (turmeric), group G (ginger), or group P (placebo) using blocked randomization and consumed three 500 mg tablets daily for five days (15 tablets total). Inflammatory markers-lactate dehydrogenase (LDH), C-reactive protein (CRP), white blood cell count (WBC), and erythrocyte sedimentation rate (ESR)-were measured at baseline and on day 6. LDH and WBC levels did not differ significantly among groups (p = 0.349 and p = 0.663, respectively). Changes in CRP and ESR varied significantly across groups (p < 0.001), with greater reductions observed in the turmeric and ginger groups compared to the placebo group (p < 0.001), and no difference between the turmeric and ginger groups (CRP: p = 0.263; ESR: p > 0.99). Turmeric and ginger exerted equivalent anti-inflammatory effects; therefore, either agent may serve as a complementary therapy alongside standard treatment to reduce CRP and ESR in COVID-19 outpatients.
