Detection of Streptococcus pneumoniae from culture-negative dried blood spots by real-time PCR in Nigerian children with acute febrile illness.
Article in BMC research notes, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectivesAcute febrile illness is a common cause of hospital admission, and its associated infectious causes, of which a key bacterial causative agent is Streptococcus pneumoniae, contribute to substantial morbidity and mortality. We sought to evaluate the utility of real-time (rt)-PCR on dried blood spots (DBS) for diagnosis of S. pneumoniae in acute febrile illness among children presenting to hospitals in Nigeria. We previously described preliminary results in a sample of 537 patients. Here we present data from a larger collection of 1038 patients.
resultsUsing rt-PCR for Streptococcus pneumoniae on 1038 dried blood spots from children prospectively enrolled with acute febrile illness, including 79 healthy controls, we detected pneumococcal DNA in nine of 15 blood culture-positive specimens, one culture-negative specimen from a high-risk group, a culture-confirmed non-pneumococcal specimen and a healthy control. Six culture-positive isolates (40%) were negative. Sensitivity was 60%, specificity 99.7%, positive predictive value 75% and negative predictive value 99.4%. Rt-PCR of DBS has limited sensitivity in blood specimens from acute febrile illness in children.
