Adverse factors on nonenhanced abdominal CT for long-term continuous ambulatory peritoneal dialysis: a comparative study between patients who withdraw from and maintain long-term peritoneal dialysis.

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
purposeTo investigate the imaging features of patients with long-term continuous ambulatory peritoneal dialysis (CAPD) on nonenhanced abdominal CT and to identify adverse factors for long-term CAPD.
methodsA total of 109 patients with less than 5 years of CAPD for peritoneal ultrafiltration failure who switched to hemodialysis (withdrawal group) and 23 patients with more than 10 years of CAPD (long-term group) were retrospectively enrolled. Nonenhanced CT manifestations in both groups were compared, including thickening and calcification of the parietal peritoneum, calcification of the mesangial margin and free margin of the small intestine wall, and calcification of the mesentery and abdominal aorta. A risk stratification model was proposed based on CT manifestations with statistically significant differences.
resultsThe presence of the following CT findings was significantly different between two groups: extensive thickening of the parietal peritoneum (78.9% vs. 21.7%, P < 0.01); severe calcification of the parietal peritoneum (60.6% vs. 8.7%, P < 0.01); calcification of the mesentery (32.1% vs. 4.3%, P < 0.05); and calcification of the free margin of the small intestine wall (49.5% vs. 13.0%, P < 0.05). However, there was no significant difference in calcification of the mesangial margin of the small intestine wall (40.3% vs. 30.4%) or in abdominal aortic calcification (56.9% vs. 61.1%) (P > 0.05). The area under the receiver operating characteristic curve (AUC) was 0.906 (sensitivity 87.6% and specificity 82.6%).
conclusionExtensive thickening of the parietal peritoneum, severe calcification of the parietal peritoneum, and calcification of the mesentery and the free margin of the small intestine wall are adverse factors for long-term CAPD.
