Evaluation of 1,030,482 Cervical Smear Results in Brazilian Population.
Article in Asian Pacific journal of cancer prevention : APJCP, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundThe objective was to determine the prevalence of abnormal cytologic smears in a large population of a Brazilian city.
methodsRetrospective study of cervical cytology results performed at a private laboratory in São Paulo - Brazil. A total of 1,030,482 cytology tests were performed between January 2010 and December 2015.
resultsAmong the satisfactory cytologies, we observed abnormal results in 8.9% (91,371). Analyzing the proportion of exams with altered results over the years, there was no change in these rates. We observed that the proportion of abnormal exams decreased with increasing age. Atypical squamous cells of undetermined significance, possibly non-neoplastic (ASC-US) cytology was the most common abnormality found in the general population with 73.19%, followed by low-grade intraepithelial lesion (LSIL) with 20.5%; these 2 cytological abnormalities add up to 93.69 % of all abnormal results. There was an increase in ASC-US with advancing age, a decrease in prevalence of LSIL, especially after the age of 30 and high-grade intraepithelial lesion (HSIL) shows two peaks of elevation, respectively in the age groups of 30-39 years and over 70 years.
conclusionWomen under the age of 30 showed a higher prevalence of cytological abnormalities, however most of these changes are low-grade lesions. In older women, cytological abnormalities are largely high-grade lesions, requiring greater care to prevent progression to cancer.
