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
purposePeritoneal Dialysis (PD) is the most common modality of renal replacement therapy in children with acute kidney injury (AKI). Various open and laparoscopic techniques for the placement of peritoneal dialysis (PD) catheter, with or without intra-abdominal fixation, have been described. The incidence of catheter migration after PD is 0-19%. We present a new, modified technique which minimizes the risk of catheter migration and blockage. MATERIALS AND
methodsFor 18 years a laparoscopic assisted PD catheter insertion has been used by the first author with a single 5 mm Port at the umbilicus using an inverted J incision and a Seldinger technique, with either a 14 or 16 Fr introducer kit. In October 2024, the technique was modified to include fixation of the catheter to the lower anterior abdominal wall using an Endoclose device (Autosuture, Covidien).
resultsSix patients- 4 boys, mean age at surgery 7.8 years- underwent PD catheter insertion using the modified technique. All patients were in End Stage Kidney Disease due to posterior urethral valves and renal dysplasia (2), nephronophthisis (1) renal dysplasia (1), focal segmental glomerulosclerosis (1) multi-cystic dysplastic kidney on one side and dysplasia on the contralateral side (1). All six cases underwent successful placement of a PD catheter. Four patients had no post-operative complications, one patient developed an incisional hernia at the Hasson port, while one patient required laparoscopic repositioning of the PD catheter and fixation to the abdominal cavity with a non-absorbable suture (2 - 0 Ethibond) at a mean follow up of 10.4 months.
conclusionThe Pedfix technique provides excellent cosmetic results, optimal pelvic visualization and fixation of the PD catheter to the lower anterior abdominal wall which minimizes the risk of catheter migration and blockage. These encouraging results need to be confirmed by a prospective study with longer follow up.
