Impact of bortezomib on 1q21+ in multiple myeloma: A meta-analysis of treatment outcomes and prognostic implications.

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 gain of chromosomal region 1q21 is a significant risk factor in multiple myeloma (MM) and is associated with poor prognosis. The introduction of bortezomib has notably improved outcomes for patients with MM. However, recent studies have reported conflicting results regarding the efficacy of bortezomib in mitigating the adverse effects of 1q21 aberration in these patients. To address this, in the present study, a meta-analysis was conducted based on 6 studies encompassing 1,575 patients with MM. The prognosis of patients with 1q21+ who underwent treatment with a bortezomib-based regimen was evaluated in terms of complete response (CR), overall survival (OS) and progression-free survival (PFS) rates. The results demonstrated that patients with 1q21 aberration were more likely to achieve CR than those without 1q21+ under bortezomib-based treatment [odds ratio, 0.64; 95% confidence interval (CI), 0.49-0.83; P=0.0008]. However, 1q21+ remained a high-risk factor in patients with MM even after bortezomib treatment [PFS: hazard ratio (HR), 1.72; 95% CI, 1.53-1.93; P<0.00001; and OS: HR, 1.95; 95% CI, 1.58-2.42; P<0.00001]. In conclusion, although bortezomib improved the likelihood of achieving CR in patients with 1q21+, this genetic aberration continues to be considered a high-risk factor in patients with MM treated with a bortezomib-based regimen.
