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

Evidence regarding rectal cancer surgery in nonagenarians remains extremely limited because most previous studies combined colon and rectal cancers despite their distinct surgical complexity and functional implications. Rectal surgery in the oldest-old is particularly challenging because pelvic dissection, anastomotic complications, and permanent stoma formation may substantially affect perioperative risk and postoperative quality of life. As population aging progresses, clarifying the feasibility and oncologic validity of rectal cancer surgery in carefully selected nonagenarians has become increasingly important.
