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

aimsThis study aimed to evaluate the impact of probiotics as an adjunct to periodontal therapy on clinical outcomes in patients with gingivitis and periodontitis through a meta-analysis of available evidence. MATERIALS AND

methodsA detailed bibliographic search on four databases (PubMed, Scopus, Cochrane and EMBASE) was conducted with a language restriction. The collected data were assessed according to the predefined eligibility criteria and randomized clinical trials reporting the effects of probiotics on plaque index (PI), bleeding on probing (BOP) and pocket probing depth (PPD) compared to control or placebo groups were selected and analysed. The risk of bias assessment was conducted using SYRCLE's RoB- 2 tool. The GRADEpro tool was used to determine the overall quality of evidence.

resultsTwenty-four studies (10 about gingivitis and 14 about periodontitis) were included in the meta-analysis. In the gingivitis studies, lower but non-significant PI and BOP were found in the probiotic group. In periodontitis, lower PI (95%-CI [- 0.54; - 0.15], p = 0.001) were reported in the probiotic group, and this difference was greater in studies with longer follow-up. Lower BOP (95%-CI [- 0.58; - 0.05], p = 0.021) was also reported, but this difference was only significant in studies with a shorter follow-up (95%-CI [- 0.86; - 0.11], p = 0.012). Meta-analysis for PPD showed lower, but non-significant, values (95%-CI [- 0.53; + 0.03], p = 0.077). However, this difference became significant when assessing studies with shorter follow-up (95% CI [- 0.77; - 0.07], p = 0.019).

conclusionsThe meta-analysis provides evidence suggested that probiotics can serve as a beneficial adjunct to periodontal treatment in patients with periodontitis, particularly in improving clinical outcomes such as plaque index and bleeding on probing. The results from gingivitis studies highlight the need for further investigation to better understand the impact of probiotics in the early stages of periodontal disease. These findings emphasize the importance of future research with standardized protocols and longer follow-up periods to confirm and expand on the clinical utility of probiotics in periodontal therapy.
