1 · What the graph read from 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.

2 · The registry

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

Denosumab is a monoclonal antibody targeting the receptor activator of nuclear factor kappa-b ligand widely used for the prevention of skeletal-related events in patients with bone metastases. This Phase 1 randomized, double-blind, two-arm, parallel-group study assessed the equivalence in pharmacokinetics (PK) and compared the pharmacodynamics (PD), safety, and immunogenicity of the proposed biosimilar RGB-14-X and reference denosumab in healthy males. Participants were randomized 1:1 to a single subcutaneous 60 mg dose of RGB-14-X or reference denosumab, with 252 days of follow-up. Primary PK endpoints were maximum observed serum concentration (C
