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
introductionAutomated peritoneal dialysis (APD) normally takes place overnight. Maintaining a stable PD catheter position, independent of body position, omental wrapping or catheter displacement secondary to bowel movements is essential in maintaining effective catheter function.
methodsWe developed a new procedure of catheter placement through combining and adapting several previously described operative techniques including laparoscopic placement of a curled double cuff Tenckhoff catheter with subcutaneous tunneling superior to the rectus sheet, an oblique course through the abdominal wall, deep entry into the pelvic peritoneum and directed placement of the curled tip within the pouch of Douglas. Retrospective analysis of catheter function was conducted, evaluating catheter position, function, complication rate and catheter survival against findings for current insertion techniques described within literature.
resultsBetween March 2009 and November 2011, 54 patients underwent PD catheter insertion. The observation period was an average of 343 ± 273 days. All patients received abdominal plain film showing optimal catheter position in 89 %. Reported catheter function was very good in 85.2 %, with no or few alarms per week during APD, moderate in 9.3 % with occasional minor dysfunctions (≤ 2 alarms per night), and poor in 5.6 %, with regular alarm disturbance. In one case, primary dysfunction led to catheter replacement. At completion, stable catheter function with occasional minor dysfunction was achieved in 52 of 54 cases. Catheter-related complications (leakage, hydrocele formation, infection and need for replacement) were observed in 14.8 %. At the end of the observation period, 55.6 % of catheters remained in use. Patient dropout occurred through death (18.5 %), renal transplantation (7.4 %), renal recovery (1.9 %), removal secondary to infection or dysfunction (9.3 %) and conversion to HD due to poor dialysis quality (7.4 %).
conclusionThe above technique combines and optimises previously described laparoscopic catheter implantation techniques, allowing increased catheter stability resulting in an undisturbed catheter function suitable for APD.
