Relationship between DMFT index and number of pregnancies: a cross-sectional study on enrollment phase of the Tabari Cohort Study.
Article in BMC oral health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundPeople of all age and gender groups are at risk of dental diseases; however, some groups, such as pregnant women, are more vulnerable than others due to their specific physiological situations. The protection of maternal and fetal is critical. Therefore, the present study intended to investigate the relationship between the Decayed, Missing, and Filled Teeth (DMFT) index and the number of pregnancies.
methodsThe present cross-sectional study was performed using the Tabari Cohort Study (T.C.S.) data. Data of 5,496 women enrolled in the T.C.S. were included in the study. After obtaining the approval of the Ethics Committee, the related data on the variables of age, age at the first pregnancy, number of pregnancies, total number of teeth at the time of examination, number of DMFT, employment status, socioeconomic status, educational level, residence location, body mass index, and the status of diabetes mellitus, hypertension, and cardiovascular diseases were extracted. Finally, data analysis was performed in the STATA software (version 14).
resultsThe mean DMFT index in women with 1, 2, 3, 4, 5, 6, and more than six pregnancies were obtained at 12.74 ± 7.11, 13.09 ± 7.06, 14.80 ± 7.81, 17.07 ± 8.11, 19.82 ± 9.02, 22.89 ± 8.98, and 26.17 ± 8.01, respectively (P < 0.001). Using the multivariate linear regression and adjusting the effect of potential confounding variables, it was found that the DMFT index increased by 34% for each unit increase in the number of pregnancies (β = 0.34, P < 0.001).
conclusionsAccording to our results, there was a significant relationship between the DMFT index and the number of pregnancies. The DMFT index was increased with an increased number of pregnancies. Therefore, oral healthcare promotion should receive special attention in healthcare planning and related policies by raising awareness and providing easy access to dental services for women of childbearing age, especially pregnant women.
