Observational studyWomen's health (London, England)
Analysis of follow-up outcomes in patients with cervical histologic low-grade squamous intraepithelial lesion preceded by serious cytology and repeated diagnosis for at least 2 years.

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
backgroundTreatment protocol for patients with cervical histologic low-grade squamous intraepithelial lesion (LSIL) such as that preceded by serious cytology and repeated diagnosis for at least 2 years is unclear.
objectiveThis study investigates the follow-up results of patients with cervical histologic LSIL and aims to provide evidence support for treatment and follow-up strategy.
designA retrospective observational study design was used.
methodsThe retrospective study included 4263 patients with cervical histologic LSIL diagnosed between August 2014 and February 2021. The follow-up period ended in August 2023.
resultsDuring the followed-up of 6-101 months, 3246 (76.1%), 628 (14.7%), and 389 (9.1%) of the 4263 patients had lesion regression, persistence, and progression. Multiple gravidities, high-risk human papillomavirus (HPV) positive, HPV 16 positive, and cytologic examination (⩾atypical squamous cells cannot exclude high grade squamous intraepithelial lesion (ASC-H)) were independent risk factors for histologic LSIL progression. The annual cumulative cervical intraepithelial neoplasia (CIN)3+ rate of patients with histologic LSIL preceded by cytologic ASC-H and gravidity >2 was 6.3% (1-year), 22.4% (2-year), 28.2% (3-year), 28.2% (4-year), and 28.2% (5-year). The cumulative CIN2+ and CIN3+ rates in patients with histologic LSIL under risk factors and repeated diagnosis for at least 2 years were significantly higher than patients preceded by cytologic negative for intraepithelial lesion or malignancy, atypical squamous cells of undetermined significance, and LSIL.
conclusionCervical histologic LSIL had a high natural regression rate and a low progression rate. Multiple gravidities, high-risk HPV positivity, HPV 16 positivity, and cytological examination ⩾ASC-H were risk factors for histologic LSIL progression. For patients with histologic LSIL preceded by cytologic ASC-H, stratified management based on the number of gravidities might be an option.
