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
Introduction: We present a case of carcinoma in situ (CIS) of the bilateral upper urinary tract (UUT) in which long-term complete remission was achieved through retrograde perfusion of Bacillus Calmette-Guérin (BCG) via open-ended ureteral catheters following the failure of endoluminal therapy using double-J stents. Case Presentation: A 52-year-old male patient was diagnosed with CIS of the bilateral UUT and bladder. Intravesical BCG instillation using double-J stents failed to eradicate persistently positive catheter urine cytology from the bilateral UUT. Since the patient strongly desired kidney-sparing treatment, retrograde BCG perfusion via open-ended ureteral catheter was performed. This treatment resulted in durable complete remission lasting 3 years. Conclusions: Retrograde BCG treatment via double-J stent may result in suboptimal efficacy due to limited drug exposure to the UUT urothelium. In cases in which kidney-sparing treatment is required, retrograde BCG perfusion via open-ended ureteral catheters may be considered a viable therapeutic option.
