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
Objectives: 1. Assess serum biomarker responses of the anterior cruciate ligament reconstructed (ACLR) knee compared to the non-injured contralateral knee in a lateral tilt paradigm. 2. Determine the relationship between kinematics at the ACLR knee and serum biomarker responses. Method: Cross-sequential study. 16 participants 2-7 years post-ACLR, undertook two 30 min walking sessions on a 10° angular tilted treadmill towards the ACLR knee and/or contralateral non-injured knee. Serum collected at baseline and after 30 min of walking was tested for biomarkers associated with osteoarthritis (Cartilage oligomeric matrix protein [COMP]), C-terminal cross-linked telopeptides of type II collagen, matrix metalloproteinase-3,-13, ADAM a disintegrin and metalloproteinase with thrombospondin motifs 4-,-5 (ADAMTS-4,-5), interleukin-1β,-6,-8 and RANTES (regulated on activation, normal T-cell expressed and secreted). Kinematic measurements were also taken. Results: When tilted towards the ACLR knee, there was a significant increase in COMP compared to baseline (mean 41.1 ng/mL (95%CI:13.8,68.4), not observed when tilted towards the contralateral knee. There was a significant correlation between change in COMP concentration and change in knee adduction/abduction angle (r = -0.58,p = 0.02). There were no relationships to kinematics and the other biomarkers. Conclusions: The tilt paradigm identified a differential response of a serum mechanosensitive marker (COMP) when testing an ACLR and contralateral knee. There was also a significant relationship between COMP response to tilt walking and the change in knee adduction angle of the ACLR knee. This paradigm could be an aid to provide individual knee biomarker response to a mechanical stress in asymptomatic individuals at risk of developing post-traumatic osteoarthritis at least 2 years post-ACLR.
