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
The aim of this study was to investigate the distribution of human papillomavirus (HPV) genotypes among cervical cancer cases in Moroccan women living in the Souss-Massa region. A total of 155 formalin-fixed, paraffin-embedded cervical tissue samples were tested for the presence of HPV DNA using a semi-nested PCR assay. HPV genotypes were identified using a direct Sanger sequencing assay. The prevalence of HPV was 85.8%. HPV DNA was found in 87.5% of high squamous intraepithelial lesions (HSIL) cases and 85.7% of invasive cervical cancer (ICC) cases. Ten distinct HPV genotypes were identified, including seven high-risk HPV (HR-HPV) genotypes and three low-risk HPV (LR-HPV) genotypes. Among HR-HPV genotypes, HPV16 was the most prevalent in both HSIL and ICC, detected, respectively, in 42.9% and 55.6% of cases. In ICC cases, HPV18 was the second most common genotype detected, in 10.3% of cases. In addition, HPV31, 33, 35, 45 and 58 were detected in 10.4% of ICC cases. LR-HPV genotypes, namely HPV62, 70 and 87, were detected in 2.4% of ICC cases. Adenocarcinoma (ADC) accounted for 4.1% of ICC cases, with HPV 16 and HPV 18 identified in 60% and 40% of these cases, respectively. Overall, our findings show that the genotypes covered by the bivalent and nonavalent HPV vaccines account, respectively, for 65.4% and 74.6%. These results highlight the importance of introducing HPV vaccination and primary HPV testing for mass screening in Morocco in order to effectively prevent and manage cervical cancer and ultimately save women's lives.
