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
objectiveHIV-Seropositive patients have higher risk of HPV infection even on anti-retroviral therapy. Infection with high-risk HPV genotypes can cause dysplasia leading to cancer. This study assessed HPV at different anatomical sites in HIV-seropositive individuals and factors associated with anal squamous intraepithelial lesions (ASIL).
methodsSpecimens were obtained from multiple anatomical sites for each participant in conjunction with routine screening for anal dysplasia. Female specimens included cervical and anal cytologies and oral wash. Male specimens included anal cytologies, oral wash, and exfoliated cells from penile head, penile shaft, scrotum, and from uncircumcised subjects, inner foreskin. Demographic and clinical characteristics were recorded. Following DNA extraction, HIV DNA copy was assessed by qPCR; HPV was genotyped. Statistical analyses included calculation of odds ratios (OR) and 95% confidence intervals (CI), t-tests or Mann-Whitney tests.
resultsMales were more likely to have ASIL: 29/50 (58%) compared to 1/11 females (9%) (OR=13.81, 95% CI: 1.64-116.32). HPV 6 or 11 in anal specimens was significantly associated with ASIL (OR= 6.29, 95% CI: 1.49-26.44). Number of HPV genotypes in anal specimens was also significant: ASIL+ (3.4 ± 3.1) versus ASIL- (1.6 ± 3.1) (p=0.009). Among 44 males, HPV was detected from at least one anatomical site for 33 participants (75%): 27 anus (61%), 19 oral wash (44%), 17 penile shaft (39%), 11 scrotum (26%), 10 penile head (23%), 0 foreskin. Detection of HPV in penile shaft specimens was significantly associated with ASIL (OR=6.79, 95% CI: 1.57-29.36) as was number of HPV genotypes in penile shaft specimens: ASIL+ (2.4 ± 4.0) versus ASIL- (0.6 ± 1.7) (p=0.025). Only 1/11 females had ASIL; only 1/11 females had cervical dysplasia: OR was not estimable due to small numbers.
conclusionsMales were more prone to ASIL than females. HPV at anal as well as non-anal sites may be indicative of ASIL.
