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

backgroundIt is unclear whether an open or laparoscopic approach results in the best outcomes for repair of umbilical and epigastric hernias. The aim of the study was to evaluate the rates of 90-day readmission and reoperation for complication, together with rate of operation for recurrence after either open or laparoscopic mesh repair for primary umbilical or epigastric hernias with defect widths above 1 cm.

methodsA merge of data between the Danish Hernia Database and the National Patient Registry provided data from 2007 to 2018 on perioperative information, 90-day readmission, 90-day reoperation for complication, and long-term operation for hernia recurrence.

resultsA total of 6855 patients were included, of whom 4106 (59.9%) and 2749 (40.1%) patients had an open or laparoscopic repair, respectively. There were significantly more patients readmitted with a superficial surgical site infection 2.5% (102/4106) after open repair compared with laparoscopic repair (0.5% (15/2749), P < 0.001. The 90-day reoperation rate for complications was significantly higher for open repairs 5.0% (205/4106) compared with laparoscopic repairs 2.7% (75/2749), P < 0.001. The incidence of a reoperation for a severe condition was significantly increased after laparoscopic repair 1.5% (41/2749) compared with open repair 0.8% (34/4106), P = 0.010. The 4-year cumulative incidence of operation for hernia recurrence was 3.5% after open and 4.2% after laparoscopic repairs, P = 0.302.

conclusionsRecurrence rates were comparable between open and laparoscopic repair of umbilical and epigastric hernias. Open repair was associated with a significantly higher rate of readmission and reoperation due to surgical site infection, whereas the rate of reoperation due to a severe complication was significantly higher after laparoscopic repair.
