Detection of chromosome 11q23 involving translocations by pulsed field gel electrophoresis.
Article in Annals of hematology, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Translocations involving chromosome band 11q23 are associated with acute lymphocytic and myelomonocytic leukemias with poor clinical prognosis. Pulsed-field gel electrophoresis (PFGE) was used to characterize the breakpoint region that has been mapped within a 300-kb fragment between the genes CD3G and PBGD. Using CD3G as a marker on SfuI-restricted DNA separated by PFGE, we detected a rearrangement involving 11q23 in the cell line B1 with a t(4;11) and in the leukemic cells of two patients, one with a t(2;11) and one with a t(11;19). In comparison, lymphoblastoid cell lines established from normal peripheral blood lymphocytes of these two patients had a normal karyotype and showed germline configuration, thus excluding RFL polymorphisms. Digestion of DNA with BssHII or SalI showed heterogeneity of 11q23 involving breakpoints. A rearrangement in the t(4;11) containing lymphoma cell line Karpas422 was seen only with the chromosome 4 probe KIT on SalI-digested DNA. PFGE is a reliable method for the mapping and detection of complex breakpoint regions. The breakpoints on 11q23 involve different introns of the highly spliced HRX/ALL-1/MLL gene.
