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
The objective was to determine if an intra-articular injection of an extracellular matrix (ECM) powder and blood composite (ECM-B) after anterior cruciate ligament (ACL) injury would have a mitigating effect on posttraumatic osteoarthritis and if that effect would be different with terminal sterilization of the ECM powder before use. Eighty Lewis rats underwent ACL transection and were divided into four groups: (1) intra-articular injection with phosphate-buffered saline (PBS; n = 20), (2) intra-articular injection of ECM-B using aseptically processed ECM (ASEPTIC; n = 20), (3) intra-articular injection of the ECM-busing ECM powder sterilized with 15 kGy electron beam irradiation (EBEAM; n = 20), and (4) intra-articular injection of the ECM-B using ECM powder sterilized with ethylene oxide (EO; n = 20). Twenty additional animals received capsulotomy only (SHAM). The animals were followed for 6 weeks and evaluations of gait, radiographs, and joint cartilage histology were performed. At 6 weeks, when compared to the SHAM group, the group treated with PBS had significantly worse gait and histologic changes, while the ASEPTIC group was not different from SHAM for either of these outcomes. When compared to the SHAM group, the EO group had similar gait outcomes, but greater histologic damage, and the EBEAM group had significantly worse gait and histological outcomes. The ECM-B composite produced using aseptically processed ECM powder mitigated the gait and histologic changes associated with osteoarthritis after ACL transection in the rat; however, care must be taken when selecting a terminal sterilization method as this may affect the effectiveness of treatment.
