1 · What the graph read from it

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.

2 · The registry

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

purposeTo detect the presence of SARS-CoV-2 in aqueous and vitreous humor of COVID-19 patients in a pilot study.

methods: Consecutive patients planned for emergency ophthalmic surgeries after ocular trauma were subjected to naso-oropharyngeal RT-PCR test for SARS-CoV-2. Laboratory-confirmed cases were enrolled for the study. During surgery, 0.1 mL aqueous and vitreous each was aspirated. The vitreous tap was collected on clinical suspicion of endophthalmitis. RT-PCR test was used to detect SARS-COV-2 nucleotide in the samples. Cycle threshold (Ct) for E gene of ≤35 along with confirmatory results on one of the two target genes (RdRp or ORF1b) was considered as positive.

results: One hundred and thirty two patients were found positive on naso-oropharyngeal RT-PCR test for SARS-CoV-2 preoperatively. Seven patients with ocular trauma were studied. The mean age was 31.8 years. There were six male and one female patient. Two patients had symptoms of mild COVID-19 disease and the rest were asymptomatic. The mean Ct value of the E gene on naso-oropharyngeal RT-PCR was 23.14 ± 4.7. Corneal and corneoscleral laceration repair was done in five patients, intracorneal wooden foreign body was removed in one patient, and injection of intravitreal antibiotics was done in one patient. Aqueous and vitreous tap was collected in 7 and 5 patients, respectively. None of the aqueous or vitreous samples was found positive for SARS-CoV-2.

conclusion: SARS-CoV-2 was not detected by RT-PCR in aqueous or vitreous humor in this pilot study. Future studies with a larger sample size are needed to further explore the presence of SARS-CoV-2 in intraocular fluids.
