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
Pleuroperitoneal communication (PPC) is a rare complication of peritoneal dialysis that often necessitates discontinuation due to recurrent pleural effusion. In some cases, the diaphragmatic defect is not visible under standard thoracoscopic inspection, making intraoperative localization challenging. Indocyanine green (ICG) fluorescence has emerged as a useful method for detecting occult fistulas. We report the case of a 51-year-old man undergoing peritoneal dialysis for end-stage renal disease who developed right pleural effusion and poor dialysate outflow three months after initiation. Radionuclide peritoneal scintigraphy demonstrated tracer accumulation in the right hemithorax, confirming PPC. Thoracoscopic inspection revealed no visible diaphragmatic defects. Following intraperitoneal injection of 1,500 mL of dialysate mixed with 25 mg of ICG, near-infrared imaging identified two focal fluorescence points on the diaphragmatic dome. These sites were closed using pledget-reinforced horizontal mattress sutures and covered with a polyglycolic acid sheet and fibrin glue. Peritoneal dialysis was successfully resumed on postoperative day seven, and the patient has remained free of recurrent effusion for two years. ICG fluorescence imaging enables rapid and minimally invasive identification of subtle diaphragmatic fistulas that may not be detectable under standard thoracoscopy. This technique may improve intraoperative localization and increase the success of surgical repair in PPC.
