Infected versus sterile abdominal fluid collections in postoperative CT: a scoring system based on clinical and imaging findings.
Article in Abdominal radiology (New York), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers, 1 of them a synthesis that pooled 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.
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
purposeCharacterization of intraabdominal fluid collections as postoperative complication is a challenging task. The aim was to develop and validate a new score to differentiate infected from sterile postoperative abdominal fluid collections and to compare it with a published score. MATERIALS AND
methodsFrom May to November 2015, all patients with postoperative CT and C-reactive protein (CRP) 24 hours before CT-guided drainage were retrospectively included (Group A). HU, gas entrapment and wall enhancement of fluid collections were evaluated in the CT. All parameters were correlated with microbiology. To validate the score and to compare it with a published score, a second patient cohort was retrospectively recruited (Group B; January 2013-April 2015; December 2015-September 2016).
resultsIn Group A (50 patients), univariate analysis confirmed that the four parameters were significantly associated with infected fluid collections. Based on binary logistic regression analysis, a score from 0 to 11 was developed (CRP </≥ 150 mg/l: 0/4 points; HU </≥ 20: 0/2 points; wall enhancement no/yes: 0/2 points; gas entrapment no/yes: 0/3 points). The best cutoff to diagnose infected fluid collections was ≥ 5 points (sensitivity 85%, specificity 79%, PPV 82%, NPV 79%). In Group B (425 patients), this score yielded sensitivity, specificity, PPV and NPV of 93%, 80%, 90% and 86%, respectively. For the published score, values were in the same range (93%, 44%, 77%, 77%).
conclusionThe score provides good discrimination between infected and sterile postoperative abdominal fluid collections. It yields comparable accuracy as the published score.
