Legionella pneumophila DNA in serum samples during Legionnaires' disease in relation to C-reactive protein levels.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Legionella pneumophila DNA can be detected in serum from patients with Legionnaires' disease (LD). We explored this observation studying the kinetics of L. pneumophila DNA in serum samples in relation to C-reactive protein (CRP). Eleven hospitalized patients with LD were studied. Diagnosis was made by Legionella urinary antigen test in 8 patients and seroconversion in 3 patients. A macrophage infectivity potentiator (MIP) real-time PCR was performed on 31 serum samples, including 20 follow-up serum samples. Serum samples obtained on the day of admission were MIP PCR-positive in 7 (64%) and MIP PCR-negative in 4 (36%) patients. Three (75%) of the 4 patients with a MIP PCR-negative serum sample on the day of admission became positive during follow-up. Overall, L. pneumophila DNA was detected in serum samples from 10 of the 11 patients (91%). CRP levels in the 7 patients with a positive MIP PCR serum sample on day of admission (499 +/- 144 mg/l; median +/- SD) were significantly higher than those in the 4 patients with a negative MIP PCR serum sample on the day of admission (244 +/- 97 mg/l). No difference in the severity of the disease on the day of admission was found between these patients. The presence of L. pneumophila DNA in serum is a common phenomenon in hospitalized patients with LD, although in some cases it is not yet present on the day of admission. L. pneumophila DNA in serum on the day of admission correlates with high CRP levels, but not with the severity of the disease.
