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
backgroundYttrium-90 ibritumomab tiuxetan [(90)Y-IT] is a CD20-targeted radio-immunotherapeutic agent. It has shown an excellent therapeutic activity with high tolerability against previously untreated follicular lymphoma (FL) and marginal zone B cell lymphoma (MZL). It is an attractive therapeutic option as the treatment schedule is short and convenient. The aim of our study is to determine the cost-effectiveness of (90)Y-IT in comparison to the standard-of-care bendamustine + rituximab (BR) in the first-line treatment of low-grade FL (LG-FL) and MZL in the real world. PATIENTS AND
methodsWe included all patients who were treated with standard-dose (90)Y-IT for previously untreated LG-FL and MZL at the Mayo Clinic Cancer Center (N = 51). A comparator arm with a historical cohort of previously untreated LG-FL and MZL patients who received BR was used (N = 92).
resultsInverse propensity weighting was utilized to balance the 2 study arms. There were no differences in terms of overall response rate (100% vs. 98%, P = .18), complete response rate (94% vs. 95%, P = .91), or 5 years progression-free survival (76% vs. 75%, P = .63) between patients who received (90)Y-IT and BR, respectively. Within the first year, patients who received (90)Y-IT required an average of 4.5 fewer oncology clinic visits (P < .001), an average of 10 fewer days of therapeutic use (P < .001), and 40% less use of growth factors (P < .001) as compared to the BR group. The direct therapeutic cost of (90)Y-IT treatment was 54% less than that of 6 cycles of BR.
conclusionThe findings suggest that (90) Y-IT is more cost-effective than BR and is a viable alternative in up-front management of LG-FL and MZL.
