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
objectiveThis study explores whether hyaluronic acid (HA) of different molecular weights and collagen, given their role in tendon extracellular matrix maintenance, have a synergistic effect on human tendon-derived cells, with the aim to improve the treatment of tendinopathy. MATERIAL: Human monocytes (CRL-9855™) and primary Achilles tendon-derived cells. TREATMENT: The collagen/HA ratio was based on the formulation of the commercial food supplement TendoGenIAL™. The anti-inflammatory activity was evaluated on human lipopolysaccharide (LPS)-stimulated macrophages (24 h) or human Achilles tendon-derived cells under basal and pro-inflammatory conditions (24 and 72 h) and on a co-culture model of tenocytes and inflamed macrophages (24 h).
resultsThese data show that the combination of high molecular weight hyaluronic acid and collagen reduces inflammation in macrophages by downregulating CD14, with a mean fluorescence intensity (MFI) of 36,274 (± 1780) (p < 0.0001). Additionally, this combination enhances the modulation of extracellular matrix remodeling proteins, such as CD44 whose MFI is 675,435 (± 28109) (p < 0.00001) and collagen type I at 17.838 µg/mL (± 6,259) (p < 0.00001). The observation of the ultrastructure of tenocytes through electron microscopy reveals increased cell membrane vesiculation and cell size, indicating that tenocytes start to proliferate and create abundant extracellular matrix proteins, important for the matrix remodeling.
conclusionsOur data confirm the anti-inflammatory activity of both hyaluronic acids and collagen, highlighting a synergistic effect of their combination in a determined ratio.
