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

A retrospective study was performed to evaluate the outcome of alendronate (ALN) treatment for seven years in postmenopausal Japanese women with osteoporosis. Forty-seven postmenopausal women with osteoporosis (mean age at baseline 65.7 years) treated with ALN for over seven years in our outpatient clinic were analyzed. Lumbar spine bone mineral density (BMD) was measured using dual energy X-ray absorptiometry, and urinary levels of cross-linked N-terminal telopeptides of type I collagen (NTX) and serum alkaline phosphatase (ALP) were monitored during the seven-year treatment period. Urinary NTX and serum ALP levels decreased (-48.2% at three months and -15.7% at seven years, respectively) and lumbar spine BMD increased (+12.8% at seven years) compared with baseline values. No serious adverse events were observed, including osteonecrosis of jaw, atypical femoral diaphysis fractures, or atrial fibrillation. To our knowledge, this is the first report of the outcome of ALN treatment for seven years in Japanese patients with osteoporosis. ALN successfully suppressed bone turnover and increased lumbar spine BMD from the baseline value over the course of the seven-year treatment period without causing any severe adverse events.
