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: The study aimed to estimate the duration of viral shedding (DVS) in patients with confirmed coronavirus disease 2019 (COVID-19), investigated the factors affecting that duration, and identified the redetectable positive (RP) cases in the recovered COVID-19 patients in Prince Sultan Military Medical City (PSMMC). Methods: The study was a retrospective record base design in the PSMMC that included 171 confirmed COVID-19 patients from 15 March to 31 May 2020. Their clinical characteristics and laboratory findings were retrieved and reviewed based on the PSMMC COVID-19 database and the Ministry of Health (MOH) Health Electronic Surveillance Network. Data analysis used the SPSS software package to measure the DVS, explore its potential factors, and identify the RP cases. The data presented as frequency distribution tables, medians, and interquartile range (IQR). Mann-Whitney U and Kruskal-Wallis tests compared the medians to explore the significant variables that affect DVS. Results: The median DVS was 11 days, IQR was 7 to 15 days, and statistically significant longer the patient presented with fever ( Conclusions: The DVS in PSMMC COVID-19 patients is comparable to the isolation period approved by MOH. Fever was a risk factor for a prolonged DVS, advised an extended follow-up period for these patients. RP cases were significantly higher among the contacts to COVID-19 cases than non-contacts. The study suggests future comprehensive research on the RP characteristics.
