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.

Abstract
Objective: This study aimed to evaluate the pharmacokinetic (PK) bioequivalence, safety, and immunogenicity of recombinant human follicle-stimulating hormone (rhFSH) for injection (code name: JZB30), developed by Chengdu Jingze Biopharmaceutical Co., Ltd., in comparison with Gonal-f® developed by Merck Serono in healthy adult Chinese female participants. Methods: single-center, randomized, open-label, two-period crossover study for bioequivalence assessment enrolled 48 healthy adult female participants, who were equally and randomly assigned to two treatment sequences. Each participant received a single subcutaneous injection of either JZB30 or Gonal-f® at a dose of 225 IU on Day 1 and again on Day 11 as part of the crossover design. Blood concentrations of FSH were measured using a validated electrochemiluminescence immunoassay, followed by non-compartmental PK analysis. Safety and immunogenicity were systematically monitored throughout the study period, including adverse events and anti-FSH antibody testing. Results: The geometric mean ratios (GMRs) of the primary PK parameters-Cmax, AUC Conclusion: JZB30 was demonstrated to be pharmacokinetically bioequivalent to Gonal-f® in healthy adult Chinese female participants, with comparable safety profiles and a low risk of immunogenicity. These findings provide evidence to support the clinical application of JZB30 as a biosimilar to Gonal-f®. Clinical Trial Registration: The trial was registered on ClinicalTrials.gov under identifier NCT06778304.
