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

Nitrogen-containing bisphosphonates have been well known to be inhibited farnesyl diphosphate synthase (FDPS), an enzyme in mevalonic acid metabolism, resulting in disturbance in polymerization of cytoskeleton structure in bone resorption and promotion of apoptosis in mature osteoclasts. Although bisphosphonates have been reported to activate ion transporters in native epithelium and Xenopus oocytes, little is known whether bisphosphonates affect acid hydrochronic acid extrusion in osteoclasts during bone resorption. The aim of this study was to determine the role of bisphosphonates on inhibition of hydrochronic acid extrusion in osteoclasts. Effects of zoledronic acid, a nitrogen-containing bisphosphonate, on the Cl(-) current activated by extracellular acidification were examined in two types of osteoclasts derived from RAW264.7 cells and mouse bone marrow macrophages (BMMs). Extracellular acidification induced outwardly rectifying Cl(-) currents in mouse osteoclasts. Zoledronic acid dose-dependently inhibited the acid-activated Cl(-) current. The non-nitrogen bisphosphonate etidronic acid had no effect on the acid-activated Cl(-) current. Tetracycline-induced FDPS silencing caused a significant decrease in the Cl(-) current. The inhibitor of geranylgeranyl transferase suppressed the Cl(-) current. By contrast, the inhibitory action of zoledronic acid was rescued by addition of geranylgeranyl acid, a derivative of mevalonic acid. The activity of acid-activated Cl(-) currents was dependent on expression of ClC-7 during osteoclastogenesis. These results suggest that nitrogen-containing bisphosphonates suppress the activity of osteoclastic acid-activated Cl(-) currents through FDPS inhibition, suggesting the inhibition of Cl(-) extrusion activity.
