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

purposeTo identify the perioperative risk factors for postoperative complications in patients aged ≥ 80 years.

methodsWe retrospectively analyzed 2,072 consecutive patients who underwent colorectal surgery at seven institutions between January 2021 and December 2023 and compared the perioperative outcomes between patients aged ≥ 80 (n = 464) and ≤ 79 years (n = 1,608).

resultsPatients aged ≥ 80 years had an American Society of Anesthesiologists Physical Status (ASA-PS) score of ≥ 3 (P < 0.0001) and more comorbidities. Minimally invasive surgery was performed less frequently (P < 0.0001), with a shorter surgical duration (P = 0.0003) and greater intraoperative bleeding (P = 0.04). Postoperative pneumonia (P = 0.0005) and urinary disorder complications after rectal surgery (P = 0.03) were more frequent in patients aged ≥ 80 years. A multivariate analysis identified male sex (P = 0.02), ASA-PS ≥ 3 (P = 0.005), and intraoperative bleeding (P = 0.02) as independent risk factors for pneumonia. Intraoperative bleeding (P = 0.002) and anastomosis (P = 0.03) were significant risk factors for urinary disorders after rectal surgery. Minimally invasive surgery in older adults resulted in a longer surgical duration (P < 0.0001), less bleeding (P < 0.0001), and fewer complications than conventional surgery.

conclusionPostoperative pneumonia and urinary complications after rectal surgery are common in older adult patients. Minimally invasive approaches may reduce the risk of complications.
