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.

Abstract

unlabelledIn the PaTH trial, among the 119 women randomized to parathyroid hormone PTH(1-84) and 60 to alendronate, we found much greater variation in BMD and markers in response to PTH(1-84) compared to alendronate. No baseline participant characteristic consistently predicted increased bone density response to PTH(1-84), although women with larger changes in 1,25 dihydroxyvitamin D during therapy had larger increases in BMD.

introductionWe examined variability in BMD and markers of bone turnover in response to treatment with PTH(1-84) or alendronate in the PaTH trial.

methodsDifferences in SD were examined using Levine's test for homogeneity of variance. Change in BMD across quartiles of participant characteristics was examined using ANOVA.

resultsWe found much greater variation in response to PTH(1-84) compared to alendronate. The SD for change in cancellous spine BMD (by QCT) was 32% on PTH(1-84) compared to 13% on alendronate (p < 0.0001). The higher variability in the PTH(1-84) group was due to substantial numbers of women with large increases in BMD on PTH(1-84). Similarly, the SD of changes in markers of formation and resorption were significantly higher on PTH(1-84) than on ALN. No baseline participant characteristics predicted increased bone density response to PTH(1-84) therapy. However, change in 1,25-OH(2)D explained 16% of the variance in BMD response to PTH(1-84).

conclusionThere is significant variability in the skeletal response to PTH(1-84), which exceeds that observed with alendronate. Changes in 1,25-OH(2)D were related to larger gains in BMD. This finding may have implications for elucidating either the pathway by which PTH affects the skeleton or traits that result in particular responsiveness to PTH therapy.
