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

questionTo investigate the association between orthodontic treatment and incidence of temporomandibular joint disorders (TMD) as a revision to the existing literature. DATA SOURCES: Electronic searches were performed in the following databases: PubMed/Medline, Scopus, Scielo, Google Scholar and Web of Science. Hand search of the references of the included studies was also conducted. STUDY SELECTION: Two authors performed database search independently using the keywords to include case control and cohort studies in English or Spanish language. Systematic reviews and Randomized controlled trials (RCTs) were excluded. DATA EXTRACTION AND SYNTHESIS: From the studies that met the inclusion criteria, investigators extracted the following data: authors, year, study title, number of patients, male/female ratio, mean age (range), follow up time, groups, number of patients per group, country and results. The Newcastle Ottawa scale was used for risk of bias assessment. All disagreements were resolved by consulting with a third reviewer.

resultsA total of 686 articles were found in the search and 28 duplicates were removed. After title and abstract screening, 648 articles remained. Ten articles were analyzed for full text and four studies were excluded in the process, leaving six articles that met all inclusion and exclusion criteria. Out of six studies, four were case control, one cohort and one prospective cohort. Authors found good quality on all categories of risk of bias assessment in the selected studies. For the meta-analysis, they considered Odds Ratio (OR) because of its presence in every included study. An association between orthodontic treatment and the occurrence of TMD was demonstrated with an odds ratio of 1.84.

conclusionsThe review authors conclude that the results of their systematic review indicate association between the orthodontic treatment and incidence of TMJ disorders.
