Trial report in Osteoporosis international : a journal established as result of cooperation between the European Foundation for Osteoporosis and the National Osteoporosis Foundation of the USA, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.

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

purposeOsteoporosis is a long-term complication of allogeneic stem cell transplantation (SCT). Receptor activator of nuclear factor-kappaB ligand (RANKL) increases osteoclast activity, while osteoprotegerin (OPG) neutralizes RANKL. A deficiency of OPG or an excess of RANKL may contribute to post-SCT bone loss.

methodsSerum OPG and soluble RANKL (sRANKL) concentrations were determined in 30 patients who received calcium, vitamin D and sex steroids--with or without pamidronate--prior to SCT and 1, 3, 6, and 12 months post-SCT and compared to those in healthy controls.

resultsDespite all treatments patients lost bone at the hip. At baseline, serum OPG was similar in patients and controls; in the two patient groups it increased by 26-27% at 6 months post-SCT (p=0.002-0.028) and over the control level (p=0.002). Serum sRANKL concentrations were also similar in patients and controls at baseline. In those patients receiving pamidronate sRANKL concentrations decreased by 42% (p=0.0007) at 3 months post-SCT. The findings on the effect of SCT on OPG and sRANKL serum levels were ascertained in 28 additional patients who did not receive pamidronate, at a median of 122 days after SCT. In this latter group, OPG but not sRANKL concentrations were clearly elevated (p<0.001) in comparison to healthy controls. In conclusion, the present study fails to support the view that an excess of sRANKL or a deficiency of OPG would have a substantial impact on bone loss in SCT-recipients.

conclusionSerum sRANKL concentrations may be modulated by bisphosphonates.
