Single-injection hyaluronic acid treatment demonstrates non-inferiority in the relief of symptomatic knee osteoarthritis: A randomized double-blind, multi-center controlled study.
Article in Osteoarthritis and cartilage open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
Objective: To compare two sodium hyaluronate formulations (HYMOVIS® ONE and MONOVISC®) for single intra-articular (IA) injection in patients with knee osteoarthritis pain. Methods: This randomized, controlled study included 347 subjects allocated to two treatment arms: HYMOVIS® ONE (n = 175) and MONOVISC® (n = 172). The primary endpoint assessed non-inferiority of HYMOVIS® ONE versus MONOVISC® based on change from baseline in the WOMAC LK3.1 A1 Pain subscale. Secondary outcomes evaluated patient response using OMERACT-OARSI criteria, changes in WOMAC stiffness and function scores, health-related quality of life (SF-12), global assessments by patients and clinicians, and rescue medication use. Results: The mean WOMAC LK3.1 A1 walking pain subscale score decreased significantly from baseline at week 12 in both groups, with reductions of 65 % for HYMOVIS® ONE and 66 % for MONOVISC®. At week 26, reductions were 73 % for HYMOVIS® ONE and 69 % for MONOVISC®. The non-inferiority test yielded a p-value of 0.0003. Clinically significant change from baseline was observed for all secondary endpoints. For the WOMAC LK3.1 Function subscale, the comparison between groups at week 26 showed a statistically significant difference (p = 0.0367) favoring HYMOVIS® ONE. Both treatments were well tolerated. Conclusions: A single injection of HYMOVIS® ONE was well tolerated and non-inferior to MONOVISC®, with improvements across all study endpoints maintained through 26 weeks, indicating sustained symptomatic relief of knee OA. Trial registration number: NCT06528600 (www.clinicaltrials.gov).
