Predictive factors of romiplostim response in patients with refractory aplastic anemia: data from two clinical trials.
Trial report in Annals of hematology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to 2 registered trials, which are not on this map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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.

Abstract
The thrombopoietin receptor agonist (TPO-RA) romiplostim has been shown to be efficacious in the treatment of aplastic anemia (AA) refractory to immunosuppressive therapy. However, there are few reports on predictors of TPO-RA efficacy. We analyzed patient clinical and baseline laboratory data from two clinical trials that enrolled patients with refractory AA, a phase 2 dose-finding study (NCT02094417) and a phase 2/3 study (NCT02773290), to determine predictors of romiplostim efficacy. Data from 66 patients (35 from the phase 2 dose-finding study and 31 from the phase 2/3 study), median age 47.0 (range 20-78) years, were analyzed. Of these, 51.5% (34/66) had non-severe AA, 86.4% (57/66) had received prior therapy with anti-thymocyte globulin plus cyclosporine, and 80.3% (53/66) were transfusion-dependent. At 27 weeks, no patients achieved a complete response, 57.4% (35/61) achieved a partial response, 49.0% (24/49) became red blood cell transfusion-independent, and 56.8% (21/37) became platelet transfusion-independent. Univariate logistic regression analysis identified duration from diagnosis (P = 0.040), baseline reticulocyte count (P < 0.001), and platelet count (P < 0.001) as predictors of response to romiplostim at 27 weeks. Receiver operating characteristic curve analysis identified a cutoff value of 30.77 × 10
