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

purposeThis study assessed the diagnostic accuracy of C-reactive protein (CRP) after gastroesophageal cancer resection for postoperative inflammatory complications (PIC).

methodsThe clinical data and CRP values of patients operated on for gastroesophageal cancer surgery between 1997 and 2009 were retrospectively analyzed. The results of this study were compared with published data using a meta-analytic approach for diagnostic outcomes.

resultsOf 210 patients included in the study, 59 developed PIC (28.1 %; 95 % CI: 22.5-34.5 %). On the postoperative day (POD) 4 and 7, CRP had the best diagnostic accuracy for PIC (AUC 0.77; 95 % CI, 0.64-0.91, AUC 0.81; 95 % CI, 0.71-0.91). Using a cut-off value of 141 mg/L (95 % CI, 131-278 mg/L) for CRP on POD 4, the sensitivity was 0.78 (95 % CI, 0.55-0.91), the specificity was 0.70 (95 % CI, 0.53-0.83) and the NPV was 0.89 (95 % CI, 0.77-0.95). The in-hospital mortality rate was 3.3 % (95 % CI, 1.5-6.9 %). In a diagnostic meta-analysis that included two additional studies, CRP had a significant predictive value after POD 3.

conclusionThere is limited evidence for the diagnostic accuracy of CRP levels for PIC after gastroesophageal cancer surgery. CRP levels on POD 4 might be useful to rule out PIC, but its diagnostic accuracy is moderate at best. For clinical routine use CRP levels are clearly not sufficient to predict PIC and have to be interpreted in the context of the whole clinical picture.
