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

objectivesResidual pockets are a risk factor of periodontitis progression. This study evaluated the efficacy of periodontal endoscopy (PE) during scaling and root planning (SRP) of residual pockets in chronic periodontitis patients after initial periodontal treatment. MATERIALS AND

methodsA single-blinded, randomized controlled clinical trial was conducted in systemically healthy subjects presenting at least three residual pockets with a probing depth (PD) ≥ 5 mm in each quadrant. Subjects were randomly allocated to one of two trial groups using a computer-generated program: SRP + PE (test group) or SRP alone (control group). Clinical parameters (PD, clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PLI)) were then measured at baseline, 3-, and 6-month follow-up.

resultsA total of 1629 sites in 37 patients were examined. Both treatments significantly improved all clinical outcomes (PD, CAL, BOP, and PLI) from baseline to 6 months (P < 0.05), although greater reductions in PD and PLI were observed in the test group at both 3- (PD: 3.45 ± 0.56 vs. 4.14 ± 0.59 mm; PLI: 0.55 ± 0.23 vs. 0.73 ± 0.27) and 6-month follow-up (PD: 3.12 ± 0.63 vs. 4.0 ± 0.68 mm; PLI: 0.49 ± 0.21 vs. 0.72 ± 0.28, respectively; P = 0.001 for PD and P = 0.021 for PLI). No significant differences in CAL or BOP were observed.

conclusionsSRP + PE resulted in significant reductions in PD and PLI compared to SRP alone in residual pockets with a PD ≥ 5 mm. CLINICAL RELEVANCE: The findings highlight the benefits of SRP + PE, supporting use as an alternative strategy in nonsurgical periodontal treatment.
