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
Background: To prevent loss of peritoneal function caused by persistent abdominal inflammation, the guidelines recommend early extubation in patients with refractory peritoneal dialysis (PD)-associated peritonitis (rPDAP). In attempt to pinpoint high-risk patient cohorts that did not respond to treatment for refractory peritonitis, we created a model to predict the effectiveness of peritonitis treatment. Methods: This observational cohort study included PD patients from 1 January 2011 to 31 December 2020. Multivariate logistic regression analysis was used to explore the factors affecting the occurrence and prognosis of rPDAP, and to construct a predictive model for the success of rPDAP treatment. Receiver operator characteristic curve, calibration and decision curve were drawn to evaluate the predictive performance of the model. Results: A total of 1397 cases of PDAP occurred in our center during the study period, of which 558 cases were diagnosed as rPDAP. The incidence of refractory peritonitis was 0.047 cases/patient-year. In the study, 440 cases with rPDAP were included. Among them, 304 cases (69.1%) had been successfully cured, while 136 cases (30.9%) were treatment failure, of which 19 cases (13.9%) died, 85 cases (62.5%) transferred to hemodialysis and 32 cases (23.5%) were relapse/recurrent peritonitis. Dialysate culture results showed 132 (30.0%) cases were infected with Gram-positive bacteria and 161 (36.6%) Gram-negative bacteria. Multivariate logistic regression analysis showed that episodes of peritonitis previously ≤3 times were correlated with the better prognosis of rPDAP, but white blood cell (WBC) counts in peritoneal dialysate on the third day of peritonitis or WBC counts on the fifth day ≥300 × 10 Conclusion: The nomogram model created through internal verification indicated a strong clinical application value and a high prognostic prediction accuracy for rPDAP.
