Efficacy of alfacalcidol and alendronate on lumbar bone mineral density in osteoporotic patients using proton pump inhibitors.
Article in Biomedical reports, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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
It has been indicated that proton pump inhibitor (PPI) use is associated with a loss of the anti-fracture efficacy of alendronate (AD). However, there are few prospective studies that have investigated the efficacy of AD on lumbar bone mineral density (BMD) in osteoporotic patients who are using PPIs. Thus, the aim of the present study was to investigate the efficacy of alfacalcidol (AC) and AD on lumbar BMD in osteoporotic patients using PPIs. A prospective, randomized, active control study enrolled such osteoporotic patients (age, ≥50 years). The patients were randomly assigned to receive AC (1 µg/day) or AD (35 mg/week) and were followed up for one year. Patient profiles were maintained, and lumbar BMD, bone-specific alkaline-phosphatase (BAP) and collagen type-I cross-linked N-telopeptide (NTX), upper gastrointestinal endoscopy results, and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) were evaluated. Percentage changes in lumbar BMD, NTX, BAP, and change in FSSG score from baseline to the end of one year of treatment were investigated. Sixteen patients were eligible for analysis (eight assigned to receive AC, eight assigned to receive AD). The percentage change in lumbar BMD from baseline to the end of treatment was -0.4±4.0% for the AC group vs. 6.8±6.3% for the AD group (P=0.015). No significant percentage change of BAP and NTX between the two groups was observed. Subsequent to one year of treatment, the FSSG score did not change from the baseline values for either study group, and no new bone fractures or esophagitis were observed in either group of patients. The findings demonstrated that in osteoporotic patients using concomitant PPIs, there was a greater increase in lumbar BMD after one year of treatment with AD compared with AC. However, the number of study subjects was small; thus, further, large prospective studies are required to determine the effect of AD in osteoporotic patients using concomitant PPIs.
