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

purposePatients with familial adenomatous polyposis (FAP) may undergo either ileorectal anastomosis (IRA) or ileal pouch anal anastomosis (IPAA) depending on the degree of rectal involvement. Desmoid tumors (DTs) may arise postoperatively. Whether IPAA is associated with a higher risk of DTs as compared with IRA remains controversial. The purpose of this study was to determine whether IPAA increased the risk of DTs by analyzing the published data that compared IRA and IPAA as the primary treatment for FAP.

methodsA metaanalysis was performed to analyze the published data between 1989 and 2019. IRA and IPAA were compared with respect to the incidence of DTs.

resultsEight retrospective studies with a total of 1072 patients were identified: 491 underwent IPAA and 581 IRA. There was no significant difference in the incidence of DTs between IPAA and IRA (11.81% vs. 9.47%, OR 0.95, P = 0.85). Meanwhile, the overall complication (42.97% vs. 36.76%, OR 1.32, P = 0.11), incidence of cancer (4.88% vs. 8.37%, OR 0.28, P = 0.26), and overall mortality (0.33% vs. 5.20%, OR 0.49, P = 0.53) were comparable too.

conclusionIleoanal pouch surgery is associated with similar risk of desmoid in patients with FAP after surgery.
