Temporal increase in the incidence of anal squamous cell carcinoma in Kentucky and factors associated with adverse outcomes.
Article in Cancer medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundAnal squamous cell cancer (ASCC) incidence in Kentucky is increasing at an alarming rate. In 2009, the incidence surpassed the US national average (2.66 vs. 1.77/100,000 people), and currently, Kentucky ranks second by state per capita. The reasons for this rise are unclear. We hypothesize individuals with ASCC in Kentucky have some unique risk factors associated with worse outcomes.
methodsIndividuals with ASCC in a population-level state database (1995-2016), as well as those treated at two urban university-affiliated tertiary care centers (2011-2018), were included and analyzed separately. We evaluated patient-level factors including demographics, tobacco use, stage of disease, HIV-status, and HPV-type. We evaluated factors associated with treatment and survival using univariable and multivariable survival analyses.
resultsThere were 1698 individuals in state data and 101 in urban center data. In the urban cohort, 77% of patients were ever-smokers. Eighty-four percent of patients had positive HPV testing, and 58% were positive for HPV 16. Seventy-two percent of patients were positive for p16. Neither smoking, HPV, nor p16 status were associated with disease persistence, recurrence-free survival, or overall survival (all p > 0.05). Poorly controlled HIV (CD4 count <500) at time of ASCC diagnosis was associated disease persistence (p = 0.032). Stage III disease (adjusted HR = 5.25, p = 0.025) and local excision (relative to chemoradiation; aHR = 0.19, p = 0.017) were significantly associated with reduced recurrence-free survival.
conclusionsThe rate of ASCC in Kentucky has doubled over the last 10 years, which is outpacing anal SCC rates in the US with the most dramatic rates seen in Kentucky women. The underlying reasons for this are unclear and require further study. There may be other risk factors unique to Kentucky.
