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
Hyaluronic acid (HA) and phospholipids (PLs) are key components of joint lubrication. In osteoarthritis (OA), the molecular weight (MW) of HA is reduced, which has been proposed to weaken the anchoring capacity of PL and impair lubrication. This study reveals a different mechanism by directly linking the MW to the structure of HA-PL (hybrid) assemblies and frictional properties. Using mixed-MW HA and PL to model this difference between healthy and OA synovial composition, we found interfacial lamellar structures form under healthy-like conditions, while hybrid vesicles predominate in OA-like conditions. At physiologically relevant shear rates, lamellar assemblies maintain ultralow friction, whereas vesicles are removed, causing a tenfold friction increase. These findings provide mechanistic insight into how HA-PL structural organization controls lubrication. While this simplified system does not capture the biochemical complexity of synovial fluid, this study advances understanding and offers a framework for designing structure-informed therapeutic strategies and biomimetic lubricants.
