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

backgroundRight colectomy (RC) is generally believed to be a simpler operation with better outcomes than left colectomy (LC). Our study was primarily intended to compare patient characteristics and perioperative outcomes between RC and LC in colon cancer patients, and secondarily to identify factors that increase the risk of developing postoperative abdominal abscess and/or anastomotic leak.

methodsUsing the 2007 Nationwide Inpatient Sample database, we evaluated patients who underwent elective RC and LC for colon cancer.

resultsA total of 50,799 patients underwent elective RC and LC for malignancy during 2007 (RC, 63.5%; LC, 36.5%). Overall, 9.6% were performed laparoscopically (RC, 9.7% vs. LC, 9.5%, P = 0.39). The majority of patients were Caucasian; 54.2% of RC and 46.5% LC patients were female (P < 0.01). RC patients were older (mean age, 70.8 vs. 65.8 years, P < 0.01) and had more comorbidities. While LC had more overall intraoperative complications (RC, 0.30% vs. LC, 1.32%, P < 0.01), RC had higher overall incidence of postoperative complications (28.43% vs. 26.75%, P < 0.01). Mean length of hospital stay (RC, 7.37 days vs. LC, 7.38 days) and in-hospital mortality (RC, 1.37% vs. LC, 1.49%) were similar in both groups. Multivariate analysis identified Native American race [adjusted odd ratio (AOR), 2.02], chronic renal failure (AOR, 1.97), congestive heart failure (AOR, 1.72), chronic pulmonary disease (AOR, 1.40), metastatic disease (AOR, 1.34), male gender (AOR, 1.23), and LC (AOR, 1.12) all independently increased the risk of abscess and/or leak.

conclusionsRC patients were older and had more comorbidities and postoperative complications. Patient characteristics and comorbidities were more important in determining overall postoperative complications than anastomotic types.
