Topical Effects of Tarragon Oil Extract on Pain Intensity, Stiffness, and Physical Function of the Knee Joint in Patients with Osteoarthritis: A Randomized Controlled 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
Background: Knee osteoarthritis is the most prevalent chronic joint condition. This study investigates the topical effectiveness of tarragon oil extract in managing knee osteoarthritis symptoms. Materials and Methods: A total of 90 eligible participants were recruited for this clinical trial through convenience sampling from patients visiting the outpatient rheumatology clinic at Taleghani Hospital in Gonbad-e Kavus, Iran. Participants were randomly divided into three groups: intervention (tarragon oil extract applied topically three times daily, every other day for 3 weeks), placebo (sweet almond oil applied topically three times daily, every other day for 3 weeks), and control (routine care). The severity of osteoarthritis was measured using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) at four time points: baseline, immediately, 1 week, and 3 weeks after the intervention period (3 weeks). Data analysis also carried out using descriptive and inferential statistics. Results: The group treated with tarragon oil extract showed a statistically significant improvement in knee joint pain, stiffness, and physical function scores immediately following the intervention compared to both baseline measures ( Conclusions: The topical application of tarragon oil extract demonstrates potential as a short-term therapeutic option for managing knee osteoarthritis symptoms, representing a complementary approach in nursing care. Nonetheless, further standardized comparative studies are required to validate its long-term efficacy.
