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

backgroundOutcomes between laparoscopic (LAPR) and open abdominoperineal resections (OAPR) are poorly described.

methodsAfter IRB approval, 2005-2008 NSQIP data were used to identify patients undergoing LAPR and OAPR for rectal cancer. Logistic regression identified variables influencing the selection of LAPR vs. OAPR as well as the likelihood of postoperative events. Chi-square analysis was used to compare the incidence of 30-day postoperative events.

resultsOne thousand one hundred ninety-seven OAPRs and 143 LAPRs were identified. LAPRs were less likely to have a body mass index (BMI) of ≥30 (p = 0.04) and were associated with equivalent mean operative times (p = 0.36). LAPRs and OAPRs were found to have similar rates of surgical site infections (p = 0.13), transfusion requirements (p = 0.17), myocardial infarction (p = 0.48), and need for reoperation within 30 days (p = 0.20). Neoadjuvant radiotherapy did not directly increase complication rates in either group. Few factors predicted choice of LAPR but included BMI <25 (OR, 1.54; p = 0.02).

conclusionComplication rates between LAPR and OAPR were similar despite the greater technical challenge of LAPR. Wound infection rates were equivalent, which may reflect similar rates of perineal wound infections. Few patients are offered LAPR, possibly due to surgeon preferance as opposed to patient factors.
