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

backgroundThe incidence of squamous cell carcinoma of the anal canal has been increasing over the last 30 years. HIV has been found to be a risk factor for the development of this disease; radio-chemotherapy (RTCT) may also be more toxic than in HIV-negative patients. The study aims at assessing whether there are any differences in terms of toxicity between HIV-positive and HIV-negative patients treated with concomitant RTCT.

methodsSearch in MEDLINE, EMBASE, CENTRAL (via Cochrane Library-Wiley), DARE, LILACS bibliographic databases. Experimental and analytical observational studies with at least two comparative arms were included: squamous-cell (SC) anal-canal cancer (ACC) treated with RTCT in HIV-positive

resultsFifteen publications, 14 retrospective studies and 1 systematic review, were found. All radiotherapy (RT) techniques and all chemotherapeutic agents used to manage this disease were included. No differences were found in terms of duration (P=0.67) and dose (P=0.53) of RT, while CT results were contradictory. Acute and hematological toxicities were significantly higher in HIV-positive patients, while gastrointestinal, dermatological and chronic toxicities did not significantly differ between the two groups. Given the high heterogeneity of the studies, no objective comparison could be made between studies that included antiretrovirals and those that did not.

conclusionsHIV-positive patients may be at higher risk for acute and hematological toxicity than HIV-negative patients. A precise conclusion cannot be drawn on the use of antiretrovirals, given the high heterogeneity of data.
