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
In this study, the effects of tranexamic acid (TXA) on the knee's articular cartilage, anterior cruciate ligament (ACL), and joint capsule were assessed histologically. There were 15 rats in each of the 3 groups, totaling 45 rats. Intraarticular (IA) saline injections were applied for the first group, IA TXA injections for the second group, and intravenous (IV) TXA injections for the third group. Using samples taken from the knee joint 3 weeks later, the medial/lateral femoral condyle and medial/lateral tibial plateau articular cartilages were evaluated with Osteoarthritis Research Society International (OARSI) scoring, while ACL diameter and joint capsule thickness were analyzed histologically. In comparisons of OARSI scores for the medial/lateral femoral condyle and medial/lateral tibial plateau cartilage regions, the scores obtained for the IV TXA group were significantly higher than those of the IA saline group (P < 0.001, P = 0.001, P = 0.003, P = 0.011). In comparisons of medial/lateral femoral condyle and medial/lateral tibial plateau OARSI scores, the scores obtained for the IV TXA group were again significantly higher than those of the IA TXA group (P < 0.001, P < 0.001, P < 0.001, P = 0.002). When ACL diameters were compared, a significant decrease was observed in the ACL diameters of the IV TXA group compared to the IA saline and IA TXA groups (P < 0.001, P = 0.039). Histologically, IV TXA damages the articular cartilage and ACL more than IA TXA. IA administration of TXA is more protective when the articular cartilage and ACL are preserved.
