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
Introduction: False-positive inconclusive polymerase chain reaction (PCR) results against severe acute respiratory syndrome coronavirus 2 were not low and have potentially harmful effects. We aimed to find parameters to differentiate positive cases from false-positive ones, and suggest an optimal scheme and follow-up period for inconclusive results. Methods: Cases with inconclusive PCR tests among healthcare personnel from February 2020 to June 2021 were classified as confirmed positive, clinically positive, and clinically negative groups, which were compared. The diagnostic accuracy of follow-up tests and composites of clinical and laboratory data were analyzed. Results: Symptoms, contact history, and lower cycle threshold of the N gene were more common in the COVID-19 positive group. The scoring schemes combining symptom and contact history with follow-up PCR results had higher sensitivities than the PCR tests only modality. Follow-up tests up to 5 days combined with symptoms and contact history could discriminate between positive and negative cases. Conclusion: A follow-up PCR test up to day 5 with clinical features might predict positivity and shorten the quarantine period in most healthcare personnel.
