Predisposing Factors for Idiopathic Granulomatous Mastitis: A Large Prospective Multicentric Study.
Article in Iranian journal of public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Background: Idiopathic granulomatous mastitis (IGM) is a chronic breast disease with unknown pathophysiological and clinical aspects. Therefore, we designed this multi-center prospective case-control study to explore and clarify the risk factors with an acceptable sample size. Methods: From March 2021 to December 2023, five hundred-four women with a histologically proven IGM were entered into the IGM group and 504 women with healthy breasts were included in the control group across nine centers. Participants' information was obtained by trained staff. Multivariate binary logistic regression was used to estimate the odds ratio (OR) and 95% confidence intervals (CI) for the associations between variables and IGM. Results: The mean age of all participants was 34.92 ± 7.12 yr. The previous history of diseases as a whole, was significantly higher in the IGM group (33.1%) compared with the control group (26.6%). Logistic regression showed that previous lactation (OR= 7.51, 95% CI= 2.37-23.77) and a positive history of diabetes (OR = 4.23, 95% CI= 1.32-13.51) had a positive association with IGM, while OCP use (OR = 0.70, 95% CI= 0.52-0.93) was associated with IGM reversely. Conclusion: The history of breastfeeding and not its duration is associated with a 7-fold increase in the rate of IGM. Furthermore, previous history of diabetes is a risk factor, while OCP use is a protective factor against IGM. We are designing another study to further investigate the relationship between breastfeeding, milk stasis, and IGM, based on our findings.
