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

BACKGROUND AND

objectiveMale osteoporosis is an important public health issue and remains undertreated. We performed this meta-analysis to clarify the anti-fracture efficacy of risedronic acid in men.

methodsRandomized controlled trials (RCTs) in men receiving risedronic acid or placebo published between 1980 and September 2008 were searched for in MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials. Studies with a follow-up of at least 12 months and providing the incidence of fractures were considered for inclusion in the review. Two independent reviewers assessed the methodological quality of the included studies and performed data extraction. Analysis of pooled data was carried out using Revman 4.2 software.

resultsFour RCTs met the inclusion criteria and permitted a pooled estimate of effectiveness. Relative risk with 95% confidence intervals for pooled effect under fixed effects model were: 0.31 (0.16, 0.60) for vertebral fractures and 0.40 (0.23, 0.70) for nonvertebral fractures, suggesting a 69% risk reduction of vertebral fractures and a 60% risk reduction of nonvertebral fracture with risedronic acid treatment in men.

conclusionThe results of this meta-analysis show that risedronic acid treatment is associated with a reduced risk of fractures in men.
