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
backgroundHuman papillomavirus (HPV) independent cervical malignancies (HPV-IDCMs) have recently been classified by the World Health Organization (WHO) 5th edition. These malignancies have historically received limited attention due to their rarity and the potential for evasion of HPV-based screening.
methodsWe retrospectively reviewed 5,854 biopsy-confirmed cervical malignancies from 22 institutions over 3 years (July 2020-June 2023). Histologic classification followed the WHO guidelines. HPV independence was confirmed by dual negativity for p16 and HPV; discordant cases (p16-positive/HPV-negative) underwent additional HPV testing using paraffin-embedded tissue. Cytological results were matched sequentially to histological confirmation.
resultsThe prevalence of HPV-IDCM was 4.4% (257/5,854) overall and was 3.6% (208/5,805 cases) among primary cervical malignancy. Patient age of HPV-IDCM was 29 to 89 years (median, 57.79). Its histologic subtypes included primary adenocarcinoma (n = 116), endometrial adenocarcinoma (n = 35), squamous cell carcinoma (n = 72), metastatic carcinoma (n = 14), carcinoma, not otherwise specified (n = 10), neuroendocrine carcinoma (n = 3), and others (n = 7). Among 155 cytology-histological matched cases, the overall and primary Pap test detection rates were 85.2% (132/155) and 83.2% (104/125), respectively. The interval between cytology and histologic confirmation extended up to 38 months.
conclusionsHPV-IDCMs comprised 3.6% of primary cervical malignancies with a high detection rate via cytology (83.2%). These findings affirm the value of cytological screening, particularly in patients with limited screening history or at risk for HPV-independent lesions, and may guide future screening protocols.
