1 · What the graph read from it

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.

2 · The registry

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

backgroundMost end-stage renal disease (ESRD) patients undergo open surgical techniques for peritoneal dialysis (PD) catheter placement. An alternative method to PD catheter implantation is the half-percutaneous ("Half-Perc") technique based on a modified trocar that is performed by a nephrologist. The single-center, retrospective, observational, cohort study presented here aimed to compare the effects of the "Half-Perc" technique with the traditional open surgery on peritoneal catheter insertion.

methodsFrom January 2015 to January 2018, 240 ESRD patients who received initial PD catheter placement were divided into two groups based on the "Half-Perc" technique or open surgery. All patients were followed up for 365 days or until loss of initial PD catheter or death. Prism 5 software was used to analyze baseline characteristics, operation-related parameters, mechanical complications and clinical outcomes.

resultsThe "Half-Perc" technique showed shorter operation time, shorter incision length, lower postoperative pain scores and quick initiation of the PD program compared to the open surgery. After the 365-day follow-up, the "Half-Perc" group showed a higher rate of catheter dysfunction (4% versus 0.9%) that was corrected by conservative treatment in most patients and a lower rate of peritonitis (4% versus 9.6%) but mechanical complications and clinical outcomes did not differ between the two groups. There was also no significant difference based on overall patient mortality or catheter removal. One-year initial catheter survival and true catheter survival were not statistically different between the groups.

conclusionThe "Half-Perc" placement of the PD catheter using a modified metal trocar appears to be a non-inferior alternative method and carries minimal invasiveness and risk compared to open surgical placement.
