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 aim of the present study was to evaluate whether serum C-reactive protein (CRP) is a useful predictor of early post-operative complications, particularly of intestinal leaks after laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery.

methodsThe present study was a retrospective analysis of a prospectively maintained database with 809 patients who underwent LRYGB from 2002 until 2011. For 410 of these patients, at least one CRP measurement within the first seven post-operative days was available. The diagnostic value was determined by the area under the curve (AUC) of the receiver operating characteristic (ROC) curve.

resultsForty-nine of 410 patients (12.0 %; 95 % confidence intervals [95 % CI], 9.2-15.5 %) developed surgery-related complications. Leaks occurred in 17 patients (4.1 %; 95 % CI, 2.6-6.5 %) at a median of 5 days after surgery. CRP levels 2 days after surgery showed the highest diagnostic value for post-operative complications (AUC, 0.74; 95 % CI, 0.60-0.89). Sensitivity was 0.53 (95 % CI, 0.31-0.74) and specificity was 0.91 (95 % CI, 0.79-0.96) on day 2 (cutoff level, 229 mg/l). The sensitivity for intestinal leaks was 1.00 (95 % CI, 0.51-1.00).

conclusionCRP on post-operative day 2 is a valuable predictor of post-operative complications, in particular intestinal leaks. Radiological imaging studies for intestinal leaks could be restricted to patients with CRP values exceeding 229 mg/l.
