Do human lymphocyte antigens play a role in the clinical antimelanoma activity of ipilimumab?
Article in Immunotherapy, 2011. 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
Evaluation of: Wolchok JD, Weber JS, Hamid O et al.: Ipilimumab efficacy and safety in patients with advanced melanoma: a retrospective analysis of HLA subtype from four trials. Cancer Immun. 10, 9-14 (2010). For the first time, a pivotal Phase III clinical trial has demonstrated an overall survival benefit for an antimelanoma drug, ipilimumab, in previously treated advanced melanoma patients. Ipilimumab is a T-cell-potentiating monoclonal antibody directed against cytotoxic T-lymphocyte antigen-4. All patients in this study were HLA-A2*0201 positive because the active control arm contained a HLA-A2*0201-restricted peptide derived from the melanocyte differentiation antigen, gp100. Hence, the following question arises: does the survival benefit conferred by ipilimumab treatment only benefit HLA-A2*0201-positive melanoma patients? However, the current paper reveals a retrospective analysis to show that advanced melanoma patients obtain a survival benefit from ipilimumab irrespective of HLA-A2*0201 status. This analysis also raises other interesting questions regarding the HLA dependence of mechanisms underlying the toxicity and antimelanoma activity of ipilimumab, which are discussed.
