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

introductionThe development of CASE PRESENTATION: A 49-year-old man with advanced rectal cancer was treated with neoadjuvant chemotherapy followed by robot-assisted ultra-low anterior resection with diverting stoma. His postoperative course was complicated by an anastomotic leak. During the diversion period, he developed fever, diarrhea, and colonic inflammation that was initially diagnosed as diversion colitis and responded dramatically to systemic steroid therapy. Following stoma closure, recurrent anastomotic ulceration and diffuse colitis developed, again showing marked steroid responsiveness. Based on the overall clinical course, the patient was considered to have a clinical course resembling UC rather than diversion colitis. The patient achieved sustained remission with systemic steroids and mesalamine, with no recurrence of intestinal inflammation or cancer.

conclusionsThis case underscores the challenges in distinguishing UC from diversion colitis in the postoperative setting. Recurrent anastomotic inflammation with pronounced steroid responsiveness should prompt consideration of underlying UC, even after colorectal cancer surgery.
