Is secondhand smoke exposure associated with poor periodontal status in children and adolescents? A systematic review and meta-analysis.

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
purposeWe aimed to systematically evaluate whether SHS exposure is associated with poor periodontal status in individuals up to 15 years.
methodsSeven databases were searched by two independent reviewers according to pre-specified eligibility criteria up to November 2021. The methodological quality of included studies was appraised using The Newcastle-Ottawa Scale and GRADE was used for assessing the certainty of evidence. Random-effects pairwise meta-analyses compared the periodontal status of those exposed and unexposed to SHS through standardized mean differences (SMDs) and associated confidence intervals (95% CI).
resultsEight cross-sectional studies were eligible for inclusion and two present high methodological quality. All studies contributed to the meta-analysis for gingival index scores (GI) and four for probing pocket depth (PPD). Those exposed exhibited significantly higher levels of GI compared to unexposed (SMD = 1.03, 95% CI 0.17-1.89), but no difference was observed for PPD (SMD = 0.34, 95% CI - 0.14-0.82), with overall very low certainty on evidence.
conclusionTherefore, very low certainty evidence supports that children and adolescents exposed to SHS possibly present poorer periodontal status due to higher levels of GI.
