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

unlabelledChanges in bone mineral density (BMD) and trabecular bone score (TBS) were assessed in 70 patients who received either zoledronate (ZOL) (n = 34) or placebo (n = 36) for 2 years. In premenopausal women with breast cancer treatment-induced bone loss, 24 months of intravenous ZOL treatment significantly increased the lumbar spine BMD and the TBS.

introductionThe aim of this study was to compare the effects of 4 mg intravenous zoledronate (ZOL) versus placebo (PLB), every 3 months, on the lumbar spine (LS) bone mineral density (BMD) and the trabecular bone score (TBS) in premenopausal women with breast cancer (BC) treatment-induced bone loss. The TBS is a gray-level texture measurement which is related to the bone microarchitecture and considered to be independent of the BMD.

methodsChanges in BMD and TBS were assessed in 70 patients who were recruited in the double-blind, placebo-controlled ProBONE-II trial and randomized to receive either ZOL (n = 34) or PLB (n = 36) for 2 years. The changes were assessed at baseline and at 12 and 24 months after treatment initiation.

resultsPatients receiving ZOL showed a mean increase in LS BMD from the baseline to 12 (2.17%) and 24 months (3.14%) of treatment and a mean increase in the TBS of 2.41 and 0.75%, respectively. Conversely, patients receiving PLB showed a mean decrease in the LS BMD from the baseline to 12 (-5.02%) and 24 (-6.43%) months and a mean decrease of -0.52 and -2.16% in the TBS, respectively. Changes in the BMD and the TBS from the baseline to 12 and 24 months were all significantly different for ZOL compared to PLB (p < 0.005). Furthermore, BMD and TBS showed a moderate correlation ranging from 0.28 (p = 0.087) to 0.47 (p = 0.003).

conclusionsIn premenopausal women with BC, 24 months of intravenous ZOL treatment significantly increased the LS BMD as well as the TBS.
