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
AMG 114 is a novel, hyperglycosylated erythropoiesis-stimulating agent. In preclinical studies, AMG 114 demonstrated increased potency and longer half-life than darbepoetin alfa and epoetin alfa. This phase I/II, randomised, double-blind, placebo-controlled, dose-escalation study evaluated safety, pharmacokinetics, and efficacy of AMG 114 in patients with non-myeloid malignancies and chemotherapy-induced anaemia. Patients were randomised (1:5) to receive subcutaneous placebo or AMG 114 Q3W for 6 weeks in 3 dose cohorts of 15 μg (cohort A1), 50 μg (cohort A2), or 200 μg (cohort A3). Safety endpoints included incidence of adverse events and dose-limiting toxicities (DLTs). The PK profile of AMG 114 was evaluated. Efficacy was assessed by change in haemoglobin from baseline to end of treatment. Forty-eight patients enrolled: 8 received placebo, 40 received AMG 114. No DLTs were observed; adverse events were consistent with underlying malignancies. The PK profile was dose-proportional over the dose range tested; terminal half-life of AMG 114 was approximately 130 h. Mean change (range) in haemoglobin from baseline in AMG 114-treated patients was -0.16 (-1.8 to 1.3), 0.21 (-1.5 to 3.4), and 0.76 (-1.0 to 2.9) g/dl in cohorts A1, A2, and A3, respectively. AMG 114 appeared to be well tolerated, but the study was halted, in part because of modest efficacy.
