Serum procalcitonin is not an early marker of pulmonary exacerbation in children with cystic fibrosis.
Trial report in European journal of pediatrics, 2012. 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
unlabelledSerum procalcitonin (PCT) has been proposed as a marker to identify bacterial infection in children. For optimal management of cystic fibrosis (CF) patients, early recognition of pulmonary exacerbations is necessary, but sensitive biomarkers to do so are lacking. Our study was done to establish baseline values for PCT in children with CF and to compare these to values at onset of a pulmonary exacerbation. Serum PCT values were determined in CF children during an outpatient clinic visit and at onset of treatment with intravenous (IV) antibiotics for a pulmonary exacerbation. Serum PCT was measured using a quantitative immunoassay (BRAHMS Kryptor PCTsensitive, Henningsdorf, Germany). In 92 outpatients (mean age 10.0 years, SD 4.8 years; mean forced expiratory volume in 1 s 91%, SD 18; 9 chronically colonized with Pseudomonas aeruginosa), mean baseline PCT was 0.05 ng/ml (SD 0.07). Mean PCT on admission for IV treatment of pulmonary exacerbation was 0.07 ng/ml (SD 0.06) (n = 22) and not different from the baseline value. PCT values were markedly higher in two CF patients with an acute nonrespiratory infection (central venous catheter-associated bloodstream infection, acute gastroenteritis), demonstrating that they can mount a PCT response.
conclusionPCT values in CF children are not different from values reported in healthy children. In CF children, PCT values do not rise significantly at the onset of a respiratory exacerbation and thus hold no promise as an early marker to identify a pulmonary exacerbation.
