Acceptability and Feasibility of Callascope Self-Imaging of the Cervix among Women in Ventanilla, Peru: A Mixed Methods Pilot Study.
Article in Journal of womens health and reproductive medicine, 2021. 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: Barriers that prevent adherence to cervical cancer screening programs in low-income communities include, among others, fear of and discomfort associated with the speculum during pelvic exams and difficulties in accessing health facilities. To address these barriers, a low-cost medical device, the Callascope was developed for self-imaging of the cervix. The device has a 2 MP camera connected to a smartphone and a disposable inserter with an asymmetrical tip to replace the speculum. A pilot study was performed to 1) evaluate the feasibility, acceptability, and comfort of women imaging their own cervix with the Callascope, 2) collect information to improve the design of the Callascope prototype, and 3) identify factors related with the ease of use, discomfort of the self-exam technique and quality of images. Methods: The pilot study included women (n=15) who were either current or former community-health volunteers from Ventanilla, Peru with the HOPE program. Participants completed a pre-exam survey to assess demographics and establish reproductive medical history. Each participant was provided with a self-exam kit. They were asked to perform a self-exam and take pictures of their cervix with the Callascope at home at their convenience. They submitted an audio reflection immediately post-examination via WhatsApp. A post-insertion survey to assess user experience and a focus group discussion were performed 72 hours post-insertion. Conclusions: The Callascope self-imaging of the cervix was reported to be more acceptable and comfortable than the traditional speculum-based gynecologic exam. All participants indicated that they would use the device again and recommend to a friend. Recommendations to improve the prototype design were identified: lengthen handle, overlay asymmetrical tip with softer silicon, and optimize manual focus mechanism. The Body Mass Index (BMI) was found to be a factor associated to the ease of device use and comfort.
