PCR as a screening test for invasive aspergillosis in haematological patients: a pilot study.
Article in Mycopathologia, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Invasive aspergillosis is a leading cause of morbidity and mortality in immunocompromised patients, particularly in individuals with haematological malignancy and in haematopoietic stem cell transplant recipients. Nowadays, the galactomannan (GM) assay has been widely used as an indication of invasive aspergillosis, even though the test is known to generate false-positive results. The aim of this study was to compare the performance of GM and real-time PCR (qPCR) to detected Aspergillus in blood samples obtained from high-risk haematological patients. Haematological patients were screened twice weekly with GM testing, which was performed by the Platelia ELISA kit. An additional sample of whole blood (4 ml) was obtained for the purpose of qPCR testing. Sixty-four samples from 12 patients with haematopoietic stem cell transplant or haematological malignancy were studied. The overall accordance between GM and qPCR tests was 96.9 % (62 samples). Only two samples showed contradictory results, with positive GM test and negative real-time PCR results. Based on the high concordance between GM and qPCR in terms of negative results, the main utility of qPCR could be in the confirmation of positive results seen with GM testing.
