Necessity for subsequent surgery in women of child-bearing age with positive margins after conization.
Article in BMC women's health, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 8 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
background20-25% of women with high-grade cervical intraepithelial neoplasias (HSIL) have residual lesions after conization. The state of the margin is generally considered to be a risk factor for recurrence or persistent lesions. Predictors of positive margins and residual lesions need to be identified. A design for postoperative management and avoidance of overtreatment needs to be provided, especially for women of child-bearing age.
methodsThis study was a retrospective analysis of 1309 women of child-bearing age with HSIL, who underwent cold knife conization (CKC). Age, gravidity, parity, human papillomavirus (HPV) species, cytology, transformation zone type, results of endocervical curettage (ECC), quadrant involvement, glandular involvement, and Cervical Intraepithelial Neoplasia (CIN) grade were analyzed. Among those with positive margins, 245 patients underwent secondary surgery within three months, including CKC, a loop electrosurgical excision procedure, and total hysterectomy. Risk factors for positive margins and residual lesions were assessed.
resultsThere was no significant difference in age, gravidity, parity, glandular involvement, and CIN grade between the two groups (P > 0.3). There was a significant difference in HPV species, cytology, ECC results, and quadrant involvement (P < 0.002). Multivariate analysis showed a major cytology abnormality, high-risk HPV infection, type III transformation zone, positive ECC result, and multiple quadrant involvement were independent risk factors for positive margins and residual lesions (P < 0.02). Age > 35 years was also a risk factor for residual lesions (P < 0.03).
conclusionHigh-risk women should be treated appropriately considering fertility. Patients with positive margins should be managed uniquely. Surgery for women without fertility may be appropriate. Close follow-up is necessary for women who have fertility requirements or are unwilling to undergo subsequent surgery if they have no risk factors, especially women < 35 years.
