Effects of Ginkgo biloba extract on periodontal pathogens and its clinical efficacy as adjuvant treatment.
Trial report in Chinese journal of integrative medicine, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 2 of them syntheses 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
objectiveTo determine the effects of Ginkgo biloba extract (EGB) on major periodontal pathogens in subgingival plaque.
methodsSixty patients with moderate to severe periodontitis were selected and randomly assigned to 3 groups: EGB group, a positive (periocline) and a negative control groups. Subgingival plaque samples were collected before treatment and 1 week, 2 months and 4 months after treatment. The detection rates of 4 major periodontal pathogens-Treponema denticola (Td), Tannerella forsythus (Tf), Prevotella intermedia (Pi), and Porphyromonas gingivalis (Pg)-were detected by polymerase chain reaction (PCR). Clinical indicators were examined before treatment, 3 and 6 months after treatment.
resultsEGB significantly decreased the detection rate of all the 4 pathogens 1 week after treatment, and then gradually increased at 2 and 4 months. EGB's inhibition effect was better than or comparable to periocline, except for Pg in short-term. The difference of plaque index (PLI) and bleeding index (BI) was not statistically significant among the groups, while for probing depth (PD) and attachment loss (AL), the difference was statistically significant between the EGB group and negative control group at 3 and 6 months after treatment.
conclusionEGB significantly inhibited major periodontal pathogens and can be used as an adjuvant for periodontitis treatment.
