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

backgroundNasopharyngeal carcinoma (NPC) is a prevalent malignancy in Asia particularly southern China. Comparisons of outcomes of conformal radiotherapy (CRT) and intensity-modulated radiotherapy (IMRT) have been still debated. This meta-analysis was carried out to compare oncologic outcomes of CRT and IMRT in the treatment of NPC.

methodsA literature search was performed through PubMed, Embase, and the Cochrane library databases from their inceptions to November 10, 2018. Two authors assessed the included studies and extracted data independently. Relative studies that compared oncologic outcomes between CRT and IMRT for NPC were included.

resultsA total of 13 eligible studies were included, which contained 1 RCT, 1 prospective study, and 11 retrospective studies. Our meta-analysis showed that IMRT has increased overall survival (OR = 0.51, 95% CI = 0.41-0.65, P < .00001), locoregional control rate (OR = 0.59, 95% CI = 0.52-0.67, P < .00001), disease-free survival (OR = 0.77, 95% CI = 0.65-0.91, P = .002), and metastasis-free survival (OR = 0.71, 95% CI = 0.54-0.94, P = .01) in comparison with CRT.

conclusionThe results of this meta-analysis indicate IMRT should be a better option for the treatment of NPC because patients who underwent IMRT may benefit from increased overall survival, locoregional control rate, disease-free survival, and metastasis-free survival compared with CRT.
