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

contextBone loss and fracture are serious sequelae of organ transplantation, particularly in the first posttransplant year. Most interventional studies have been inadequately powered to detect effects on fracture.

objectiveThe objective of the study was to determine whether treatment with bisphosphonates (BP) or active vitamin D analogs (vitD) during the first year after transplantation reduces fracture risk and estimate the effect of these interventions on bone loss. DATA SOURCES: Sources included PUBMED, MEDLINE, Cochrane Library, and abstracts from scientific meetings (presented 2003-2010). STUDY SELECTION: Randomized controlled clinical trials of BP or vitD in solid organ transplant recipients were included if treatment was initiated at the time of transplantation and fracture data were collected. DATA EXTRACTION: Two investigators independently extracted data and rated study quality. Fixed effect and random-effects models were used to obtain pooled estimates. DATA SYNTHESIS: Eleven studies of 780 transplant recipients (134 fractures) were included. Treatment with BP or vitD reduced the number of subjects with fracture [odds ratio (OR) 0.50 (0.29, 0.83)] and number of vertebral fractures, [OR 0.24 (0.07, 0.78)]. An increase in bone mineral density at the lumbar spine [2.98% (1.31, 4.64)] and femoral neck [3.05% (2.16, 3.93)] was found with treatment. When BP trials (nine studies, 625 subjects) were examined separately, there was a reduction in number of subjects with fractures [OR 0.53 (0.30, 0.91)] but no significant reduction in vertebral fractures [OR 0.34 (0.09, 1.24)].

conclusionsTreatment with BP or vitD during the first year after solid organ transplant was associated with a reduction in the number of subjects with fractures and fewer vertebral fractures.
