Review in Journal of Taibah University Medical Sciences, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT07091578 (Assessing the Feasibility of School-Based Oral Health Programmes in Primary Schools in Saudi Arabia), which is not on this map. Cited by 40 papers.

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.

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.

Abstract

objectivesIn KSA, numerous studies are conducted to measure the prevalence of dental caries. However, the prevalence of dental caries varies in KSA. This systematic review aims to improve the understanding of the prevalence of dental caries among adults and children residing in KSA.

methodsOnline databases of MEDLINE, EMBASE, and the Cochrane Library were searched. The Saudi Dental Journal was hand-searched. Study selection and data extraction were conducted in duplicate. The studies on dental caries in the Saudi population were included. The Newcastle-Ottawa Scale (NOS) was used to assess the quality of the selected studies. Finally, a narrative synthesis was conducted.

resultsForty-nine cross-sectional studies were identified. Areas of weakness in study design/conduct were low response rates, reliable outcome measurement, and identification and handling of confounding factors. Statistical pooling of data was not appropriate due to substantial heterogeneity, also in part to a variation in geographical location and the target population. Twenty-nine studies presented data for primary dentition. The proportion of dental caries among primary teeth ranged from 0.21 to 1.00. Eighteen studies presented data for permanent dentition. The proportion of dental caries across permanent teeth ranged from 0.05 to 0.99.

conclusionsIn general, the methodological quality of the included studies was poor. Dental caries proportion level ranged from 0.05 to 0.99 in permanent teeth, and 0.21 to 1.00 across primary teeth. The available data does not provide a complete assessment of dental caries across KSA. Existing studies are limited in terms of the populations studied for dental caries.
