1 · What the graph read from it

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.

2 · The registry

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

We analyzed the immunoglobulin (Ig) variable heavy (IGHV) and variable light chain genes used by leukemia cells of 258 unrelated patients with chronic lymphocytic leukemia (CLL) found to express unmutated Ig heavy chains (IgH) encoded by a 51p1 allele of IGHV1-69 among 1846 CLL patients examined. We found each had at least 98% homology to an identified germline IGKV or IGLV gene. Within the 258 IgH, we identified heavy chain CDR3 (HCDR3) motifs encoded by certain unmutated IGHD and IGHJ genes with restricted reading frames. Frequent and restricted use of particular IGKV and IGLV genes revealed nonstochastic pairing of disparate Ig light chains (IgL) with IgH that had restricted HCDR3 motifs designated CLL69A, -B, -C, and -D. Eighty-six percent (19/22) of CLL cases that expressed motif CLL69B encoded by IGHD2-2/IGHJ6 had distinctive IgL encoded by IGKV1-39. Similarly, 83% (5/6) of samples with motif CLL69D encoded by IGHD2-2/IGHJ6 expressed IGKV3-11, 100% (25/25) with motif CLL69A encoded by IGHD3-16/IGHJ3 used IGKV3-20, and 77% (10/13) with motif CLL69C encoded by IGHD3-3/IGHJ6 expressed IGLV3-9. This study reveals nonstochastic pairing of IgH with particular IgL that is predicated upon Ig HCDR3 structure, providing compelling evidence for selection of antibodies expressed in CLL by conventional antigens.
