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
background and purposeDistinguishing branchial cleft cysts (BrCCs) from cystic metastases of human papillomavirus (HPV) positive tonsillar or base of tongue squamous cell carcinoma and cancer of unknown primary (CUP) is challenging. Fine needle aspiration cytology (FNAC) from cystic metastasis can be nonrepresentative, while reactive squamous cells from BrCC can be atypical. It is unclear whether benign characteristics and the absence of HPV-DNA in FNAC can enhance distinguishing BrCC from a cystic metastasis; therefore, we investigated here. PATIENTS/MATERIALS AND
methodsMorphology and HPV-DNA in FNAC were reevaluated preoperatively and correlated to final diagnosis of 304 BrCC and CUP patients at Karolinska University Hospital during 2016-2023. RESULTS AND
interpretationAll 176 cases finally diagnosed as BrCC were HPV-DNA negative in the preoperative FNAC. HPV-DNA was present in 100/128 (78.1%) of the FNAC with a solitary cystic neck metastasis and in 3/3 CUPs separately investigated on surgical specimens, which is distributed in 40/58 (69.0%) CUP, 40/41 (97.6%) tonsillar cancer, 21/22 (95.5%) base of tongue cancer, 2/2 uterine cervical cancer, and 0/5 non-HPV-related cancers.
interpretationAll cases with final BrCC diagnosis were HPV-DNA negative in FNAC. HPV-DNA was only present in FNAC of malignant cystic neck masses of HPV-related tumors or CUP. The data suggest that HPV-DNA analysis in FNAC enhances the diagnostics of cystic masses of the neck. A FNAC with a benign morphology and the absence of HPV-DNA indicated a BrCC, while an HPV-DNA positive aspirate irrespective of morphology suggested an HPV-DNA positive cancer or CUP.
