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

backgroundThere is a lack of consensus in current practice guidelines regarding routine neuroimaging in patients with stage IV non-small cell lung cancer (NSCLC) without neurologic symptoms, and there is a paucity of data on the impact of such imaging on overall survival (OS).

methodsThis retrospective study included 257 patients with stage IV NSCLC without neurologic symptoms diagnosed between January 1, 2013 and December 31, 2016 at

resultsCNS imaging, mainly with computed tomography (CT), was performed at diagnosis in 56% of patients, and the prevalence of synchronous CNS metastasis among these patients was 32%. There was no difference in median OS between patients who underwent initial CNS imaging and those who did not, but we did show a tendency for a higher cumulative incidence of metachronous CNS metastasis in patients without baseline imaging. These metachronous metastases were symptomatic and were more often not treated when compared to synchronous metastases.

conclusionsIn this small, unicentric retrospective study, there was no benefit with routine neuroimaging in terms of median OS in stage IV NSCLC patients without neurologic symptoms.
