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
contextCurrent phenotypic techniques for extended spectrum beta lactamase (ESBL) detection can be interpreted after 24 h of incubation only, resulting in a delay in initiating therapy. Nordmann, Dortet, and Poirel (NDP) in 2012 proposed a novel test named ESBL NDP to overcome this limitation.
aimsThis study aimed to evaluate the ESBL NDP test for the identification of ESBL among SETTINGS AND
designThis cross-sectional study was conducted over a period of 3 months on a sample size of 100. SUBJECTS AND
methodsOne hundred nonduplicate clinically significant
resultsThe phenotypic confirmatory test and the ESBL NDP test were positive in 82% and 63% of the isolates, respectively. ESBL NDP test had a sensitivity and specificity of 76% and 100%, positive and negative predictive values of 100% and 48%, respectively, kappa value of 0.54 (moderate agreement), and 95% CI for kappa of 0.43-0.66. The time to positivity was 1 h in 93.6% of the isolates.
conclusionThe NDP test showed a good specificity, with time to positivity of 1 h. The low sensitivity could be due to the difference in the phenotypic type of ESBL producer and technical reasons.
