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

objectiveStage N2-3 nasopharyngeal carcinoma (NPC) shows a high risk of distant metastasis, which will finally cause death. This study aimed to evaluate the impact of neoadjuvant chemotherapy (NACT) of various cycles before radical radiotherapy on distant metastasis and survival of patients with stage N2-3 diseases.

methodsIn this study, a total of 1,164 consecutive patients with non-metastatic N2-3 NPC were recruited and prospectively observed. Then 231 patients who received NACT of 4 cycles (NACT=4 group) were matched 1:2:1 to 462 patients treated with NACT of 2 cycles (NACT=2 group) and 231 patients treated without NACT (NACT=0 group), according to age, histological subtype, N stage and NACT regimen. Five candidate variables (sex, T stage, concurrent chemotherapy, intensity-modulated radiation therapy and cycle number of NACT) were analyzed for their association with patients' survival.

resultsAfter matching, the overall survival (OS), disease-free survival (DFS), local-recurrence-free survival (RFS) and distant-metastasis-free survival (MFS) of the NACT=4 group (89.2%, 81.0%, 83.3% and 84.8%, respectively) were better than those of the NACT=2 group (83.3%, 72.5%, 81.2% and 77.9%, respectively) and the NACT=0 group (74.0%, 63.2%, 74.0% and 68.8%, respectively). In multivariate analysis, the cycle number of NACT maintained statistical significance on the OS, DFS, RFS and MFS (all P<0.05).

conclusionsFor N2-3 NPC, cycle number of NACT appeared to be an independent factor associated with an improvement of survival.
