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

Osteoporosis treatment in patients undergoing maintenance dialysis remains to be established. Sequential romosozumab-to-denosumab therapy improved bone mineral density and suppressed bone turnover. Shorter transition periods were associated with reduced TRACP-5b rebound, highlighting the importance of transition management and suggesting this approach as a promising option for this high-risk population. PURPOSE: Patients on dialysis have a higher risk of fractures than the general population. However, osteoporosis treatment in patients on dialysis has not been established. We aimed to evaluate the efficacy of sequential therapy with romosozumab followed by denosumab and examine the clinical impact of the transition period between these agents.

methodsIn this retrospective multicenter cohort study, 34 patients on maintenance dialysis received romosozumab for 12 months followed by denosumab for 12 months. Endpoints included lumbar spine and femoral neck bone mineral density and bone turnover marker levels. The transition period between the two agents was analyzed in relation to rebound of tartrate-resistant acid phosphatase 5b level.

resultsSequential therapy improved bone mineral density (lumbar spine: 0.797-0.997 g/cm²; femoral neck: 0.490-0.537 g/cm² p < 0.001) and the corresponding T-scores (lumbar spine: -2.1 to -0.9; femoral neck: -3.0 to -2.7; p < 0.001). Bone turnover marker levels also improved, including a marked decrease in tartrate-resistant acid phosphatase 5b levels. However, as both agents may induce hypocalcemia, we implemented an internal protocol involving strict monitoring of parathyroid hormone and serum calcium levels. Consequently, some patients required a longer interval before transitioning from romosozumab to denosumab. A longer transition period was associated with greater rebound of tartrate-resistant acid phosphatase 5b level, particularly when the interval exceeded 4 months.

conclusionThe sequential therapy was associated with significant improvements in bone mineral density and bone turnover marker levels among patients on dialysis. Timely transition between agents appears critical to maintain suppression of bone resorption.
