Systematic review and meta-analysis of the antioxidant capacity of lycopene in the treatment of periodontal disease.
Synthesis in Frontiers in bioengineering and biotechnology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This systematic review with meta-analysis evaluated the antioxidant effect of lycopene as an adjuvant treatment for periodontal disease. PubMed, EMBASE and Web of Science databases were consulted. According to the PICOs strategy, inclusion criteria were established for intervention studies Randomized Controlled Trials in Probing depth subjects (participants) treated with conventional treatment and lycopene (intervention) compared to patients treated with conventional treatment (control) in which periodontal response to treatment (outcome) was assessed. The risk of bias for randomized studies was assessed using the Cochrane Risk of Bias Tool. The methodological quality of the studies included in the meta-analysis was measured using the Jadad scale. Quantitative data were analyzed using six random-effects meta-analyses, taking into account periodontal parameters: Probing Pocket Depth, Clinical Attachment Loss, Bleeding on Probing, Plaque Index, Uric Acid and Gingival Index. Six further meta-analyses were performed, according to the follow-up of the studies (short-, medium- and long-term). Of the 339 studies identified, only 7 met the eligibility criteria. The meta-analysis of the studies according to the parameters evaluated only obtained statistical significance in the assessment of plaque index (
