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
objectiveTo investigate the clinicopathological characteristics and factors influencing the prognosis of non-Hodgkin lymphoma (NHL) in oral and maxillofacial regions.
methodsClinicopathological data of 369 patients with oral and maxillofacial NHL initially diagnosed in Peking University Hospital of Stomatology from 2008 to 2020 were collected and analyzed retrospectively.
resultsThere were 180 males and 189 females. The median age of the patients was 56 years (3 months to 92 years), and the median duration was three months. Clinically, 283 cases manifested as mass, 38 cases as ulcerative necrotizing lesions, and 48 cases as diffuse soft tissue swelling. The lesions of 90 cases located in face and neck (75 cases neck, 20.3%), 99 cases were of major salivary glands (79 cases parotid glands, 20.9%), 103 cases of oral cavity, 50 cases of maxillofacial bones, 20 cases of Waldeyer's ring, and 7 cases of infratemporal fossa. In the study, 247 of the 369 patients had cervical lymphadenopathy, only 40 cases had B symptoms, and 23 cases had the bulky disease. Of the 369 NHLs, 299 (81%) were B-cell NHL, and 70(19%) were T-cell NHL. Diffuse large B-cell lymphoma, extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue, follicular lymphoma, and extranodal natural killer (NK)/T-cell lymphoma nasal type were the most common pathological subtypes. According to Ann Arbor staging, 87, 138, 106, and 38 cases were classified as staged Ⅰ, Ⅱ, Ⅲ, Ⅳ, respectively. The me-dian follow-up time was 48 months, 164 patients died during the follow-up period. The overall survival rates for one year, two years, and five years were 90.1%, 82.4%, and 59.9%, respectively, and the median survival was (86.00±7.98) months. Multivariate analysis showed that age (
conclusionOral and maxillofacial NHL has unique clinical characteristics and distribution patterns of pathological subtypes. Fewer patients had systemic symptoms. Neck and parotid glands were the most common sites invaded by NHL. Advanced age, Ann Arbor stage Ⅲ-Ⅳ, B symptoms, and T-cell NHL may predict a poor prognosis in oral and maxillofacial NHL patients.
