1 · What the graph read from it

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.

2 · The registry

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 cancer is a rare entity and the effect of gender and HPV status on survival is controversial. We aimed to evaluate the difference in overall survival (OS) according to gender and analyzed the effect of HPV status on OS. PATIENTS AND

methodsThe National Cancer Database (NCDB) was queried for patients with anal squamous cell carcinoma between 2004 and 2016. We evaluated the OS based on gender and HPV status using Kaplan-Meier estimates and we used multivariate Cox regression analyses to evaluate factors associated with overall survival.

resultsA total of 6133 patients with known HPV status were included for analysis. In the non-metastatic group, male gender was associated with worse OS (HR 1.50, 95% CI 1.32-1.70; P<0.001) whereas HPV status did not affect the OS (HR 1.08, 95% CI 0.96-1.22; P=0.213). In the metastatic group, there was no difference in OS based on gender (HR 1.29, 95% CI 0.91-1.82; P=0.148), whereas HPV-negative status was associated with worse OS (HR 1.52, 95% CI 1.09-2.12; P=0.014).

conclusionFemales had better OS only in non-metastatic anal squamous cell carcinoma (ASCC). HPV-negative status was associated with worse OS only in metastatic ASCC.
