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
The genome of the gut protozoan parasite Giardia duodenalis (assemblage A) has been sequenced and compiled as contigs and scaffolds (GiardiaDB- http://GiardiaDB.org ), but specific chromosome location of all scaffolds is unknown. To determine which scaffolds belong to the 3-Mb chromosome, a library of probes specific for this chromosome was constructed. The probes were hybridised to NotI-cleaved whole chromosomes, and the combined size of different NotI segments identified by the probes was 2,225 kb indicating the probes were well distributed along the 3-Mb chromosome. Six scaffolds (CH991814, CH991779, CH991793, CH991763, CH991764, and CH991761) were identified as belonging to the 3-Mb chromosome, and these scaffolds were ordered and oriented according to scaffold features including I-PpoI sites and hybridisation pattern. However, the combined size of scaffolds was more than 4 Mb. Approximately, 1 Mb of scaffold CH991763 carrying previously identified sequences specific for the 1.5-Mb chromosome(s) including subtelomeric sequence was reassigned, and several other anomalies were addressed such that the final size of the apparently 3-Mb chromosome is estimated to be 2,885 kb. This work addresses erroneous computer-based assignment of a number of contigs and emphasises the need for alternative and confirmatory methods of scaffold construction.
