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
Objectives: To explore a possible difference in the histology of the minor salivary glands in the peritonsillar space between patients with peritonsillar abscess, acute tonsillitis, or tonsillar hypertrophy. To compare if there were remnants of possible changes in elevated serum amylase and its isoenzymes between these three groups to clarify the ambiguous etiology of peritonsillar abscess. Methods: This is a cross-sectional study, in which we analyzed 75 tonsil and blood samples collected from patients with peritonsillar abscess, acute tonsillitis, or tonsillar hypertrophy prior to tonsillectomy. Histological findings of minor salivary glands in peritonsillar space were examined. Serum C-reactive protein, serum amylase, and its isoenzymes (pancreatic type and the salivary type) were analyzed from blood samples collected in conjunction with tonsillectomy. Results: Minor salivary glands were present in 62 (82.7%) tonsil samples. Peritonsillar abscess group exhibited more periductal inflammation in the minor salivary glands (85.0%) than in the acute tonsillitis (70.6%) or hypertrophy group (28.0%) ( Conclusion: Peritonsillar abscess patients had more periductal inflammation in the minor salivary glands than acute tonsillitis or hypertrophy patients, suggesting that peritonsillar abscess may originate from an infection of the minor salivary glands. Blood samples for amylase isoenzymes should be collected during the acute phase of the disease to obtain additional information about the link between peritonsillar abscess and minor salivary gland activity. Level of Evidence: 3.
