Prevalence and management of invalid GeneXpert enterovirus results obtained with cerebrospinal fluid samples: a 2-year study.
Article in Journal of clinical microbiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
A total of 525 cerebrospinal fluid (CSF) samples submitted during the 2007 and 2008 enteroviral seasons were included in a study to determine the prevalence of and potential risk factors for invalid Cepheid GeneXpert enterovirus assay (GXEA) results, as well as possible solutions for the problem. The invalid GXEA results were reported for 43 (8.2%) specimens and correlated with increased visibility of red blood cells (P < 0.0001) but not with CSF xanthochromia and clotting. Invalid GXEA result rates were markedly diminished by 82.1% and 96.0% and test sensitivities were minimally decreased by 1.7% and 3.6% when these specimens were tested at a 1:5 dilution and after a freeze-thaw cycle, respectively.
