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
Purpose: This study aimed to assess the relationship between the preoperative reactive oxygen species and free ferrous protoporphyrin (ROS and FH) combined test and the risk of recurrence in a pathologically confirmed non-muscular invasive bladder cancer (NMIBC) patients. Patients and Methods: The retrospective study included 218 patients, newly diagnosed with NMIBC between January 2019 and February 2022. According to the results of FH and ROS combined test of voided urine, all patients were classified as FH(-)/ROS(-), FH(+)/ROS(-), or FH(+) /ROS(+). We reviewed demographic information, pathological results, and the FH and ROS combined test status. The clinicopathological characteristics were evaluated, and the survival rates of each group were compared. Finally, we also analyzed the association between preoperative free ferrous protoporphyrin and reactive oxygen species status and the tumor stage and grade. Results: This study included 218 NMIBC patients with a median age of 68 years (interquartile range [IQR] 60-76 years). The number and proportion of patients in FH(-)/ROS(-), FH(+)/ROS(-) and FH(+) /ROS(+) were 95(43.6%), 79(36.2%) and 44(20.2%), respectively. And the pathological stages for those with FH(+) and ROS(+), FH(+) and ROS(-), FH(-) and ROS(-) at diagnosis were 0.5% Tis, 6.4% Ta, 13.3% T1; 2.3% Tis, 20.6% Ta, 13.3% T1; 5.5% Tis, 28.9% Ta, 9.2% T1, respectively. After adjusting for clinical factors, including tumor grade, tumor stage and FH/ROS status were independent risk factors for RFS In the multivariate Cox regression analysis. Through logistics regression analysis, FH(+)/ROS(+) were found to be corelated with high grade and more high stage (T1). Kaplan-Meier analysis showed that 1-year RFS of FH(+)/ROS(+), FH(+)/ROS(-) and FH(-)/ROS(-) were 46.0%, 87.8% and 93.4%, respectively (P=0.000). Conclusion: In newly diagnosed NMIBC patients, the status of FH(+)/ROS(+) has an association with a higher risk in recurrence. Furthermore, FH(+)/ROS(+) at diagnosis was correlated with high grade and higher stage (T1). Hence, the FH/ROS combined test can help specify treatment options for patients diagnosed with NMIBC.
