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
Phage therapy is emerging as a promising alternative to antibiotics for treating various infections. However, there have been no prior studies on using bacteriophages for peritonitis in patients undergoing peritoneal dialysis. This report presents the successful treatment of refractory peritonitis in a 71-year-old male peritoneal dialysis patient using bacteriophages combined with antibiotics. The patient has a history of refractory and repeat peritonitis caused by Staphylococcus haemolyticus, which was resolved through simultaneous catheter replacement (SCR). Subsequently, the patient experiences another episode of refractory peritonitis due to Klebsiella pneumoniae. Although this strain is found to be susceptible to amikacin and imipenem, a 14-day course of treatment with these antibiotics in the abdominal cavity fails to resolve the peritonitis. Combined with antibiotic therapy, the patient is successfully treated with intraperitoneal phage therapy targeting his bacterial isolate. We monitor the longitudinal progression of phage loads, phage-neutralizing antibodies, interleukin-6 levels, and lipopolysaccharide concentrations in the dialysate effluent during the bacteriophage therapy. The combination of a phage cocktail and imipenem (IPM) demonstrates a greater effect in killing bacteria than either treatment alone, which indicates that a synergistic effect exists between the phage cocktail and IPM. Intraperitoneal IPM is discontinued after a 3-week course of treatment. At the same time, oral fluconazole is given to prevent fungal infections. The patient is discharged without any antibiotics. After this round of treatment, the patient remains healthy during the one-month follow-up. Our study suggests that personalized phage therapy combined with sensitive antibiotics can play a significant role in managing refractory peritonitis in patients undergoing peritoneal dialysis, showing promise for future applications.
