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 use of surgery in patients with colorectal cancer (CRC) aged ≥90 years remains controversial. This study aimed to evaluate the short-term postoperative and long-term oncologic outcomes of CRC surgery in patients within this age group.

methodsA total of 151 consecutive nonagenarian patients who underwent CRC surgery were included from 3 different hospitals. The Comprehensive Complication Index (CCI) was used to grade postoperative complications. Univariate and multivariate analyses were conducted to identify factors associated with CCI and overall survival (OS).

resultsThe patients had a mean age of 92.8 years (standard deviation ±1.9 years). Forty-six patients (30.5%) underwent emergency surgery, and 105 patients (69.5%) underwent elective surgery. The postoperative complications rate was 66.2% (100/151), and the mean CCI was 26.3 (±30.8). Twenty-three patients (15.2%) died postoperatively, and the perioperative mortality rates for elective surgery and emergency surgery were 7.6% (8/105) and 32.6% (15/46), respectively (P<0.001). The 1-, 3-, and 5-year survival rates were 77.5%, 53.9%, and 38.6%, respectively. Multivariate analysis revealed emergency surgery and American Society of Anesthesiologists (ASA) score to be predictors of postoperative complications. Advanced tumor stage, palliative surgery, ASA score ≥4, and CCI >17 were associated with poor OS.

conclusionsCRC surgery should not be denied to nonagenarian patients. Surgical treatment can be performed with acceptable morbidity and mortality, and achieves long-term survival in a select group.
