Randomized Trial of Lower-Dose Roxadustat Efficacy and Safety in Non-Dialysis-Dependent CKD-Associated Anemia.
Article in Kidney international reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Introduction: Different starting doses of roxadustat are used for treating anemia in chronic kidney disease (CKD). We tested the noninferiority of weight-based lower starting dose compared with standard starting dose roxadustat for anemia in stage 3 to 5 CKD without dialysis. Methods: Patients were randomized (1:1) and stratified by CKD stage to receive weight-based standard (< 60 kg: 70 mg 3 times per week [TIW]; ≥ 60 kg: 100 mg TIW) or 1-step-lower (< 60 kg: 50 mg TIW; ≥ 60 kg: 70 mg TIW) roxadustat starting dose for 16 weeks. The primary endpoint was mean hemoglobin change from baseline over weeks 12 to 16. The secondary endpoints included the proportion achieving hemoglobin 100 to 120 g/l, hemoglobin variability, and rescue therapy. Results: Overall, 254 patients were randomized. The mean (SD) baseline hemoglobin was 89.88 (6.90) g/l. Most patients had stage 4 (39.0%) or stage 5 (40.2%) CKD. Mean hemoglobin increased from baseline at weeks 12 to 16 (lower: 21.57 g/l; standard: 26.35 g/l), but noninferiority was not met. A comparable proportion achieved hemoglobin of 100 to 120 g/l (lower: 46.0%; standard: 47.2%). The hemoglobin increase was comparable in CKD stage 3 to 4, but less with the lower dose in CKD stage 5 (17.28 vs. 26.71 g/l). The lower dose exhibited a lower hemoglobin rate of change (lower: 2.917; standard: 3.376) and less drug exposure. Drug-related adverse event rates were comparable. Conclusion: The proportion of patients who achieved the hemoglobin target was comparable between the doses. The lower starting dose had less hemoglobin fluctuation and is recommended for stage 3 to 4 CKD.
