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
Group II introns are self-splicing RNAs that also act as retroelements in bacteria, mitochondria, and chloroplasts. Group II introns were identified in Escherichia coli in 1994, but have not been characterized since, and, instead, other bacterial group II introns have been studied for splicing and mobility properties. Despite their apparent intractability, at least five distinct group II introns exist naturally in E. coli strains. To illuminate their function and learn how the introns have dispersed in their natural host, we have investigated their distribution in the ECOR reference collection. Two introns were cloned and sequenced to complete their partial sequences. Unexpectedly, southern blots showed all ECOR strains to contain fragments and/or full-length copies of group II introns, with some strains containing up to 15 intron copies. One intron, E.c.14, has two natural homing sites in IS629 and IS911 elements, and the intron can be present in one, both, or neither homing site in a given strain. Nearly all strains that contain full-length introns also contain unfilled homing sites, suggesting either that mobility is highly inefficient or that most full-length copies are nonfunctional. The data indicate independent mobility of the introns, as well as mobility via the host DNA elements, and overall, the pattern of intron distribution resembles that of IS elements.
