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

purposeThis study was aimed to compare lymphatic complications of bipolar vessel sealing system with silk ligation of lymphatic vessels among renal transplant recipients.

methodsThis was a prospective randomized controlled trial done among 68 patients undergoing renal transplantation in Tribhuvan University Teaching Hospital. They were randomly assigned to either silk ligation or Enseal bipolar vessel sealing lymphatic dissection. Postoperative drain volume and duration of drain placement were measured in all patients. Ultrasound was used to find lymphocele formation in six and 12 weeks.

resultsTotal of 30 patients in silk ligation group and 28 patients in bipolar vessel sealing group were analyzed. The baseline characteristics of the patients in each group were similar. Overall, lymphatic complications (either lymphorrhea or lymphocele formation) were in 16 cases (27.58%), 7 (25%) in the bipolar group, and 9 (30%) in the silk ligation group (p = 0.67). A total of 13 patients (22.41%) had lymphorrhea, 6 (21.4%) patients in the bipolar group, and 7 (23.3%) patients in the silk ligation group. Median drain volume was 415 ml (Q1 275 ml, Q3 675 ml) in the bipolar group and 542 ml (Q1 290, Q3 775) in silk group (p = 0.72). Median drain removal day was 5 in each bipolar and silk group with Q1 and Q3 being 5 days in each arm (p = 0.95). A total of five patients (8.62%) developed symptomatic lymphocele, two (7.1%) in the bipolar group, and three (10%) in the silk ligation group, but the difference was not statistically significant. In univariate analysis, double renal arteries in the donor's kidney (p = 0.03) and graft rejection (p = 0.04) were risk factors for the development of lymphatic complications. However, in multivariable analysis, these factors were not statistically significant.

conclusionsThis study did not find any significant differences in lymphatic complications between bipolar vessel sealing system and silk ligation. However, large sample multi-centric studies should be done to add evidences on lymphatic complications differences between these two techniques.
