Effect of alendronate on the progression of periodontitis induced by Porphyromonas gingivalis and Fusobacterium nucleatum: a study in rats.
Article in Clinical oral investigations, 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
objectiveThe study aimed to investigate the effect of alendronate (ALN) on the inhibition of alveolar bone loss in experimental periodontitis in Wistar rats. MATERIALS AND
methodsPeriodontitis was induced by oral inoculation of Porphyromonas gingivalis with Fusobacterium nucleatum. The rats (n = 80) were randomized as follows: negative control (n = 10); positive control (n = 10); ALN groups: test 8 (n = 10), test 12 (n = 10), and test 16 (n = 10); and placebo groups: control 8 (n = 10), control 12 (n = 10), and control 16 (n = 10). Two milligrams per kilogram of ALN or placebo was administered twice weekly for 8, 12, and 16 weeks. Bone loss was determined by morphological and histological analyses. One independent, blinded examiner (ICC, 0.91) performed the measurements. The distance from the cement enamel junction to the alveolar bone crest of the second lower molar was measured: distal-vestibular (d), furca (f), mesial-vestibular (h), and area. Histometry was performed on the second contralateral molar. Sections (6 μm) were used to determine the furcation bone area (A-FB). The following statistical analyses were conducted: Mann-Whitney and Kruskal-Wallis.
resultsPC group developed periodontitis (p < 0.0001). Morphometric analysis determined that ALN was effective in T8 for linear measurements d, f, and h (p < 0.05). No significant differences occurred at test 8, test 12, and test 16. Analysis of A-FB revealed no significant differences between the ALN and placebo groups at 8 and 16 weeks (p > 0.05). ALN was effective against bone loss in relation to A-FB after 12 weeks (p < 0.0001).
conclusionsAccording to the methodology used, the results suggest that oral administration of ALN could influence alveolar bone loss in rats submitted to experimental periodontitis. CLINICAL RELEVANCE: ALN could be a potential therapeutic approach when associated with periodontal treatment.
