Molecular analysis of the 16S-23S rDNA internal spacer region (ISR) and truncated tRNA(Ala) gene segments in Campylobacter lari.

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
Following PCR amplification and sequencing, nucleotide sequence alignment analyses demonstrated the presence of two kinds of 16S-23S rDNA internal spacer regions (ISRs), namely, long length ISRs of 837-844 base pair (bp) [n = six for urease-negative (UN) Campylobacter lari isolates, UN C. lari JCM2530(T), RM2100, 176, 293, 299 and 448] and short length ISRs of 679-725 bp [n = six for UN C. lari: n = 14 for urease-positive thermophilic Campylobacter (UPTC) isolates]. The analyses also indicated that the short length ISRs mainly lacked the 156 bp sequence from the nucleotide positions 122-277 bp in long length ISRs for UN C. lari JCM2530(T). The 156 bp sequences shared 94.9-96.8 % sequence similarity among six isolates. Surprisingly, atypical tRNA(Ala) gene segment (5' end 35 bp), which was extremely truncated, occurred within the 156 bp sequences in the long length ISRs, as an unexpected tRNA(Ala) pseudogene. An order of the intercistronic tRNA genes within the short nucleotide spacer of 5'-16S rDNA-tRNA(Ala)-tRNA(Ile)-23S rDNA-3' occurred in all the C. lari isolates examined.
