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 optimal radiation field of chemoradiation therapy (CRT) for stage I esophageal squamous cell carcinoma (ESCC) is unknown. This retrospective study compared efficacy and safety of two CRT modalities, involved field irradiation (IFI) and elective nodal irradiation (ENI), when treating patients with clinical stage I (T1bN0M0) ESCC.

methodsPatients had received 60 Gy CRT concurrently with 5-FU and cisplatin between January 2000 and December 2012. The clinical target volume of IFI was limited to the primary tumor plus a 2-cm craniocaudal margin; that of ENI covered the primary tumor plus the field of regional lymph nodes.

resultsOne hundred and ninety-five patients were selected (IFI group, 78; ENI group, 117). The 5-year overall, cause-specific and progression-free survival rates were 90.5%, 91.6% and 77.6% in the IFI group, and 72.5%, 88.3%, 57.9% in the ENI group, respectively. Of recurrent patients (n = 16 in the IF and n = 33 in the ENI groups) after achieving complete remission, 12 (75%) in the IFI group received definitive salvage therapy, 11 (33%) patients did in the ENI group. More patients died of diseases other than esophageal cancer in the ENI group (n = 29, 25%) than in the IFI group (n = 3, 3.8%). Multivariate analysis identified ENI (HR 3.63 [1.78-7.38], p < 0.001), age ≥ 70 (HR 2.65 [1.53-4.58], p < 0.001) and PS = 1 (HR 2.36 [1.33-4.18], p = 0.003) as poor prognostic factors for OS.

conclusionsIF irradiation would be better than ENI for the patients with stage I ESCC who received definitive chemoradiotherapy.
