Altered macrophagic THP-1 cell phagocytosis and migration in bisphosphonate-related osteonecrosis of the jaw (BRONJ).

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
objectivesLocal immune dysfunction via macrophages is a proposed aetiology of bisphosphonate-related osteonecrosis of the jaw (BRONJ). This study aimed to clarify the effects of various bisphosphonates on macrophage function using a THP-1 monocytic model to examine migration, phagocytosis, and fibrin structure. MATERIALS AND
methodsTHP-1 cell migration was measured in the presence and absence of zoledronate, ibandronate, risedronate, alendronate, pamidronate (0.5, 5 and 50 μM) and clodronate (125, 250 and 500 μM) using the real-time xCELLigence system. Phagocytosis and actin fibre assays were performed after 72 h with zoledronate, ibandronate, alendronate and clodronate.
resultsTime to maximum migration for THP-1 cells was significantly reduced (p < 0.05) for high dosages of zoledronate, ibandronate and alendronate compared to controls. All dosages of clodronate and a low dose of zoledronate exhibited prolonged migrations. Phagocytic capacity was significantly reduced in high dosages of all bisphosphonates and for 5 μM zoledronate and ibandronate (p < 0.05). Low bisphosphonate exposure was accompanied by overcharged phagosoms. Altered appearance in F-actin fibrin structure was observed in bisphosphonate-exposed cells.
conclusionsAll bisphosphonates altered the migration of THP-1 cells dose-dependently. Low doses also prolonged migration and altered cell morphology. These findings support the idea of a disturbed local immune function of macrophages even in jaw bone exposed to low concentrations of bisphosphonate. CLINICAL RELEVANCE: These are the first real-time results for disrupted migration and function of macrophagic THP-1 cells in high doses. Low dosages also demonstrated altered macrophage phagocytosis and cell morphology, suggesting a disturbed local immune function in BRONJ pathogenesis.
