The stage of head and neck diagnosed malignancies in COVID-19 outbreak versus before outbreak: A retrospective study.
Article in Cancer reports (Hoboken, N.J.), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundGlobal COVID-19 pandemic has affected cancer care systems. Recent studies show that the number of cases diagnosed with cancer has drastically decreased compared to the same period before the pandemic. Therefore, we are confronted with delayed diagnosis of critical cancers.
aimThe aim of this study is to investigate whether the stage of known cancers has been affected by delayed diagnosis and to compare the stages of head and neck cancers diagnosed during and before the pandemic.
methodsThe present study was conducted on 132 patients with malignant head and neck tumors referred to the otolaryngology, head and neck cancer department of Taleghani Hospital from 2019 to 2021. The stage of cancers was compared between two groups of patients with head and neck malignancy referred to the Otolaryngology, Head and Neck Department of the Taleghani Hospital before and during the COVID-19 outbreak.
resultsThe results from tumor (T), nodes (N), and metastases (M) (TNM) staging (p-value = .015) and T score (value = 0.045) showed that the stage of tumor diagnosed in patients during the COVID-19 pandemic significantly increased compared to patients diagnosed with a tumor before pandemic.
conclusionIn the present study, it was observed that the early symptoms of malignant head and neck tumors have been neglected by patients during COVID-19 pandemic and resulted in delayed diagnosis. This result may be explained by the fear of COVID-19 infection in patients, which discouraged them from visiting a doctor at healthcare centers.
