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

backgroundThe number of patients with ulcerative colitis (UC) is increasing rapidly in Asia. No large study has evaluated the clinical outcomes of hand-sewn ileal pouch-anal anastomosis (IPAA). This study aimed to create a large database of the surgical outcomes of UC, present the trends of surgical procedures, and evaluate the impact of minimally invasive procedures on UC.

methodsData of patients first treated from 2005 to 2019 were collected; two-staged surgery data were extracted, and minimally invasive surgery (MIS) and open surgery (OS) outcomes were compared using propensity-score matching.

resultsThe data of 1558 cases were selected as the main analysis set. The number of surgical cases of UC has been increasing, with increasing proportion of MIS cases (2005: 43%, 2019: 84%). The median age of the patients increased in these 15 years (39.5-56 years old). Of 873 patients who underwent two-staged surgery, after 3:1 matching, 408 MIS and 176 OS cases were compared. Hand-sewn anastomoses were performed in 293 MIS (72.0%) and 142 OS-IPAA (80.7%) cases. The proportion of early complications (≥ Grade 3) did not vary between the two groups. Intraoperative blood loss was lower and blood transfusions were less frequent in the MIS group.

conclusionsThe proportion of MIS for UC has rapidly increased over the past 15 years. The total number of MIS and OS complications did not vary significantly between the groups. The short-term advantages of MIS include reduced blood loss and less necessity for blood transfusions.
