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

backgroundEarly-stage oropharyngeal squamous cell carcinoma (OPSCC) can currently be treated by surgical resection or definitive radiotherapy (RT). The aim of this study is to review the outcomes of early-stage OPSCC submitted to surgery or primary RT. Preliminary results have shown similar overall survival (OS) and locoregional recurrence-free survival (LRFS). MATERIAL/

methodsRetrospective study of patients with cT1-T2 cN0-N1 OPSCC, diagnosed between January 2009 and December 2014, treated with surgery or primary RT.

results61 patients with cT1-T2 cN0-N1 OPSCC were included. Forty-two (69%) were submitted to surgical resection, of which 37 (88%) had adjuvant treatment (24 received RT and 13 chemoradiotherapy). Nineteen (31%) were treated with primary RT, and 3 of them had concurrent chemotherapy. RT was given with intensity-modulated radiation therapy (IMRT) (71%) or three-dimensional conformal radiation therapy (3D-CRT) (29%). At a median follow-up of 5.4 years, there were 3 tumor persistences, 5 local failures, 2 regional failures and no distant metastasis. The 3-year and 5-year OS were 77% and 71% in the RT group vs. 71% and 59% in the surgery group, respectively (HR 0.60, 95% CI 0.22-1.61;

conclusionsLonger follow-up still does not show a significant difference in OS and LRFS between both treatments. Because most patients submitted to surgery required adjuvant RT and since its side-effects were not negligible, further studies are warranted to better suit the first treatment for each patient and to prevent the need for adjuvant treatment and the risk of toxicity.
