A randomized multi-centre study on the effectiveness of non-surgical periodontal therapy in general practice.
Trial report in Journal of clinical periodontology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02168621 (Approaches to Pocket/Root Debridement for Periodontal Infection Control - a Study on Effectiveness.), which is not on this map. Cited by 11 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.

Abstract
aimTo evaluate the effectiveness of two non-surgical treatment protocols for periodontitis patients in general dental practice. MATERIALS AND
methodsNinety-five dental hygienists (59 dental clinics) were randomly assigned to one of two treatment protocols: (i) establishment of adequate self-performed oral hygiene prior to a single session of ultrasonic instrumentation (guided periodontal infection control [GPIC]) or (ii) conventional non-surgical therapy (CNST) including patient education and scaling and root planing integrated in multiple sessions. Residual pockets at 3 months were retreated in both groups. The primary outcome was pocket closure (probing pocket depth ≤ 4 mm) at 6 months. Multilevel models were utilized.
resultsBased on data from 615 patients, no significant differences with regard to clinical outcomes were observed between treatment protocols. Treatment-related costs (i.e., chair time, number of sessions) were significantly lower for GPIC than CNST. Smoking and age significantly affected treatment outcomes.
conclusionsNo significant differences between the two approaches were observed in regard to clinical outcomes. GPIC was more time-effective. Patient education should include information on the detrimental effects of smoking. CLINICALTRIALS: gov (NCT02168621).
