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
Objective: Prolonged nasopharyngeal carriage of SARS-CoV-2 has been linked to prolonged hospital stay and delayed radiologic recovery. To determine if clinical risk factors are associated with prolonged nasopharyngeal carriage or longer hospital stay, we performed a descriptive analysis of 169 moderate to severe COVID-19 patients admitted at the Philippine General Hospital from March to June 2020. Methods: Length of nasopharyngeal RT-PCR positivity and clinical demographic data were extracted from existing patient records. Chi-square test, Mann-Whitney U test, and regression analysis were performed to describe the association of clinical risk factors with prolonged nasopharyngeal carriage and length of hospital stay. Results: The median duration of carriage was 19 days (IQR 12.0-30.0 days). No comorbidities or inflammatory markers had a statistically significant association with prolonged nasopharyngeal carriage defined as >24 days of nasopharyngeal RT-PCR positivity. Characteristics associated with a statistically significant longer hospital stay included chronic kidney disease stages 3-5, severe disease, and use of empiric antibiotics on admission. Prolonged carriage >24 days, hsCRP, and D-dimer at admission, also had a statistically significant but weak correlation with length of stay. Conclusion: Among patients with moderate disease, comorbidities and inflammatory markers were not associated with prolonged COVID-19 nasopharyngeal carriage. Prolonged nasopharyngeal carriage >24 days was associated with longer hospital stay, while D-dimer and hsCRP levels at admission, also had statistically significant but small effects on increasing the hospital length of stay.
