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

unlabelledIn a study of 2005 institutionalized older people, use of oral bisphosphonates was associated with a 27% reduction in risk of death compared to non-users after adjusting for potential confounders.

introductionThis study investigated whether reductions in mortality reported in a trial of intravenous zoledronate after hip fracture could be seen in older people taking oral bisphosphonates.

methodsTwo thousand and five institutionalized older people (mean age 85.7 years) were assessed at baseline and followed up for hip fracture and death for at least 5 years. Cox proportional hazards regression was used to estimate effects of bisphosphonates on risk of death.

resultsAt baseline, 78 subjects were taking oral bisphosphonates. Over 5 years of follow-up, 1,596 participants (80%) died. Use of bisphosphonates was associated with a 27% reduction in risk of death compared to non-users after adjusting for age, gender, type of institution, immobility, number of medications, weight, cognitive function, co-morbidities, and hip fracture incidence during the follow-up period (hazard ratio 0.73; 95% CI, 0.56 to 0.94; P = 0.02).

conclusionOral bisphosphonates are associated with a reduction in the risk of death in the elderly. The mechanism of effect requires further investigation.
