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.

Abstract

backgroundProlonged postoperative ileus (PPOI) is among the common complications adversely affecting postoperative outcomes. Predictors of PPOI after major abdominal surgery remain unclear, although various PPOI predictors have been reported in patients undergoing colorectal surgery. This study aimed to devise a model for stratifying the probability of PPOI in patients undergoing abdominal surgery.

methodsBetween 2012 and 2013, 841 patients underwent major abdominal surgery after excluding patients who underwent less-invasive abdominal surgery, ileus-associated surgery, and emergency surgery. Postoperative managements were generally based on enhanced recovery after surgery (ERAS) program. The definition of PPOI was based on nausea, no oral diet, flatus absence, abdominal distension, and radiographic findings. A nomogram was devised by evaluating predictive factors for PPOI.

resultsOf the 841 patients, 73 (8.8%) developed PPOI. Multivariable logistic regression analysis revealed smoking history (P = 0.025), colorectal surgery (P = 0.004), and an open surgical approach (P = 0.002) to all be independent predictive factors for PPOI. A nomogram was devised by employing these three significant predictive factors. The prediction model showed relatively good discrimination performance, the concordance index of which was 0.71 (95%CI 0.66-0.77). The probability of PPOI in patients with a smoking history who underwent open colorectal surgery was calculated to be 19.6%.

conclusionsColorectal surgery, open abdominal surgery, and smoking history were found to be independent predictive factors for PPOI in patients who underwent major abdominal surgery. A nomogram based on these factors was shown to be useful for identifying patients with a high probability of developing PPOI.
