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

Abstract
Background This study aimed to observe the relationship between aortic calcification and the primary patency rate of new autologous internal fistulas in maintenance hemodialysis patients and to explore the possibility of predicting the dysfunction of autologous internal fistulas using the aortic calcification score. Methodology A total of 75 patients who underwent autologous arteriovenous fistula and hemodialysis for the first time in our hospital between January 2016 and December 2019 were selected. Abdominal aortic calcification index (ACI) was recorded at the time of internal fistula establishment. Patients were divided into high- and low-calcification groups based on the ACI results. The primary patency rate of autologous internal fistulas in the two groups was observed over five years. Results Of the 75 patients, 70 (93.33%) had varying degrees of aortic calcification, with 37 patients in the high calcification group (ACI > 10%). During the five-year follow-up period, 64 patients developed internal fistula dysfunction due to various causes, including 35 cases of thrombosis and 19 cases of fistula stenosis. At 12, 36, and 60 months, the primary patency rates of internal fistulas in the low calcification group were 92.5%, 57.5%, and 17.5%, respectively, whereas those in the high calcification group were 85.7%, 30.4%, and 9.1%, respectively. The difference in primary patency rates between the two groups was statistically significant after five years (F = 4.443, p = 0.035). Cox analysis showed that autologous internal fistula dysfunction was related to ACI (hazard ratio = 2.114, 95% confidence interval = 1.146-3.899, p = 0.017). Conclusions A higher aortic calcification score was associated with dysfunction of the autologous arteriovenous fistula within five years. Patients with higher aortic calcification scores require more frequent monitoring of the internal fistula function and early intervention to prolong the service life of the internal fistula.
