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
objectiveThis study assessed the feasibility of smartphone-based colposcopy (SBC) for visual inspection of the cervix by community healthcare workers in low-resource areas.
methodsThis was a retrospective study conducted in community villages in rural Vietnam, where 177 participants were enrolled for a cervical cancer screening. Cervical images were obtained by pre-trained community healthcare workers using a portable, upcycled SBC (Samsung Galaxy Note 20). Images were taken before and after the visual inspection after acetic acid (VIA) examination. Captured images were stored on a web server through an Android-based application and later reviewed independently by two experienced gynecologists. Image quality was assessed, and kappa statistics were calculated for the measurement of agreement in VIA findings.
resultsCervical images of 177 women obtained between July and August 2020 were analyzed. The mean age of women was 42 ± 9.1 years, and 20.3% were postmenopausal. The percentage of adequate visibility of the squamocolumnar junction (SCJ) in the captured images was 83.1%. The kappa value for interobserver reliability was 0.61 for VIA positivity agreement between the two gynecologists. Image clarity was rated as average or above in 77.3%. The reasons for suboptimal clarity were poor focusing (15.3%), inadequate SCJ visibility (18%), and obscuring of the transformation zone due to blood (11.3%), discharge (14.7%), or artifacts such as intrauterine devices or polyps (5.1%).
conclusionUpcycled SBC was feasible when performed by pre-trained healthcare workers in a low-resource setting. VIA findings by SBC showed adequate agreement between two independent assessments, suggesting its potential as a method to aid cervical cancer screening.
