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
MspNI and MspNII, isoschizomers of prototype Type II restriction endonucleases AvaII and BstYI, were extracted from an extreme thermophile bacterium belonging to the genus Meiothermus, isolated from the hot sulphur springs in north Himalayan region of India where temperature and pH ranged from 60 to 80°C and 7.5 to 8.5, respectively. The two enzymes were purified to homogeneity using Cibacron-Blue 3GA Agarose, Q-Sepharose and SP-Sepharose chromatography and were homodimers with subunit molecular weights of 27 and 45 kDa, respectively. Restriction mapping and run-off sequencing of MspNI and MspNII cleaved pBR322 DNA showed that they recognized and cleaved 5'-G/GWCC-3' and 5'-R/GATCY-3' sites, respectively. MspNI and MspNII worked optimally at 60 and 70°C, 6 and 5 mM MgCl(2), respectively and showed no star activity in organic solvents. Both were resistant to sequence methylation and were stable up to 25 PCR cycles.
