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
backgroundFew studies have reported a possible involvement of pleiotrophin (PTN) in the pathophysiology of osteoarthritis (OA) and very little is known about its role in rheumatoid arthritis (RA). This study is to measure PTN in the sera and synovial fluids in RA and OA and to assess its relation to activity, functional class and radiological staging. SUBJECTS AND
methodsSerum and synovial fluid samples were collected from 35 RA patients and 40 knee OA patients and serum samples were withdrawn from 20 healthy controls. Demographic, clinical and serological data were prospectively assessed. Functional and radiographic grades were also assessed. Serum and synovial fluid PTN levels were measured using enzyme-linked immunosorbent assay (ELISA).
resultsThere was no statistical significant differences (p > 0.05) on comparing the mean PTN level in sera of RA, OA patients and healthy controls. However the mean synovial fluid level of PTN in both patient groups was significantly higher than mean serum level (p < 0.001). Significant correlations between the serum PTN level and both morning stiffness duration (p = 0.008) and mHAQ score (p = 0.039) were only observed in RA patients.
conclusionOur results point to a possible important role of PTN in RA and OA. We firstly report a serological pattern of PTN in the sera and synovial fluids of RA patients. However its implementation as a disease marker or a potential target therapy in both diseases awaits larger studies and further investigations.
