Efficacy and safety of curcumin in patients with hand osteoarthritis: a pilot double-blinded randomised controlled trial.
Trial report in BMC complementary medicine and therapies, 2025. 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
backgroundCurcumin, a substance in Turmeric spices, has been shown to exhibit anti-inflammatory and chondroprotective properties in several preclinical studies. However, there is limited research on the efficacy and side effects of oral curcumin in treating hand osteoarthritis. Thus, the primary aim of this pilot study was to assess the therapeutic effects and potential adverse effects of curcumin in patients with hand osteoarthritis, specifically in terms of pain reduction, improvement in functional outcomes, and relevant blood test parameters.
methodThis pilot prospective double-blind, randomized controlled trial included patients over 50 years old diagnosed with hand osteoarthritis. Participants received a three-month oral administration of either a turmeric capsule containing curcumin (170 mg/day) or a placebo. The outcomes measures included the Visual Analogue Scale (VAS) for pain, the Disabilities of Arm, Shoulder, and Hand (DASH) score, hand grip and pinch strength, as well as side effects and blood tests at one, two, three, and six months.
resultsTwenty-seven patients were enrolled in this study-13 in the curcumin group and 14 in the placebo group. Baseline characteristics were similar between both groups. Although patients in the curcumin group showed reductions in VAS pain scores and improvements in DASH scores after one month, the differences were not statistically significant. However, by the third month, patients in the curcumin group demonstrated significant reductions in VAS pain scores at rest and during activity compared to the baseline scores, with mean differences of 1.37 ± 0.64 (p-value = 0.032) and 1.74 ± 0.73 (p-value = 0.017), respectively. Additionally, their DASH scores improved significantly with a mean difference of 11.84 ± 5.88 (p = 0.044). One patient in the curcumin group experienced gastrointestinal (GI) side effects, leading to withdrawal from the study, but no other adverse effects were reported.
conclusionBased on the results of this pilot study, the authors conclude that a three-month regimen of low-dose oral curcumin may improve pain and functional scores in patients with hand osteoarthritis compared to placebo. However, GI discomfort remains a potential side effect to monitor. Overall, curcumin appears to be a safe and feasible alternative treatment option for hand osteoarthritis, and a larger, definitive randomised controlled trial is warranted.
