Comparison of results generated by serotyping, pulsed-field restriction analysis, ribotyping, and repetitive-sequence PCR used to characterize penicillin-resistant pneumococci from the United States.

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
One hundred forty-seven isolates of Streptococcus pneumoniae with high-level penicillin resistance collected during a national surveillance program in the United States were characterized by serotyping, pulsed-field restriction analysis, ribotyping, and repetitive-sequence (BOX element) PCR. The results generated by each method were compared by frequency of association to examine whether relationships existed between the various typing methods and statistically to determine association with the geographic source of the isolate or the age of the patient from whom the isolate was obtained. When the data were examined by pairwise analysis of individual strain classifications produced by each typing method, no statistically significant relationships between strain type, geographic location, or patient age were identified, suggesting that distinct clones of penicillin-resistant S. pneumoniae have been widely distributed throughout the United States. However, we did observed shared expression of two or three typing markers at a high frequency (>50%) among clusters of strains, indicating a certain level of concordance between the various typing methods used to classify penicillin-resistant S. pneumoniae.
