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

introductionCell sheets consisting of adipose-derived stem cells (ADSCs) have been reported to be effective for wound healing. We conducted this study to clarify the efficacy of ADSC sheets in wound healing at the duct-to-duct biliary anastomotic site in pigs.

methodsEleven female pigs (20-25 kg) were divided into two groups: biliary anastomosis with an ADSC sheet (n = 6) or without an ADSC sheet (n = 5). To follow the transplanted ADSCs, PKH26GL-labeled sheets were used in one of the ADSC pigs. Two weeks prior to laparotomy, ADSCs were isolated from the lower abdominal subcutaneous adipose tissue. After three passages, ADSCs were seeded on temperature-responsive culture dishes and collected as cell sheets. ADSC sheets were gently transplanted on the anastomotic site. We evaluated specimens by PKH26GL labeling, macroscopic changes, infiltration of inflammatory cells, and collagen content.

resultsLabeled ADSCs remained around the bile duct wall. In the no-ADSC group, more adhesion developed at the hepatic hilum as observed during relaparotomy. Histopathological examination showed that the diameter and cross-sectional area of the bile duct wall were decreased in the ADSC group. In the no-ADSC group, a large number of inflammatory cells and more collagen fibers were identified in the bile duct wall.

conclusionsThe present study demonstrated that autologous ADSC sheet transplantation reduced hypertrophic changes in the bile duct wall at the anastomotic site. A long-term follow-up is required to evaluate the efficacy of this mechanism in prevention of biliary anastomotic strictures.
