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

introductionThe efficacy of tyrosine kinase inhibitors (TKIs) with and without radiotherapy (RT) has not been determined in patients with brain metastases from epidermal growth factor receptor-mutant TKI naïve non-small cell lung cancer (NSCLC).

methodsBetween 2008 and 2016, 586 patients were diagnosed with NSCLC and treated with TKIs at a hospital in Seoul, South Korea; 81 of these patients met the eligibility criteria for our study. Outcomes analyzed included intracranial progression (ICP), neurological death, and overall survival (OS).

resultsThe 2-year cumulative incidence of ICP was 36.5% in the TKI plus RT group and 62.2% in the TKI alone group (P = 0.006). The chronological pattern analysis indicated that 64.3% of ICP developed within 12 months of the start of TKI treatment in the TKI alone group. The multivariate analysis revealed that treatment group (P = 0.003) and duration of TKI treatment ≤ 12 months (P < 0.001) were significantly associated with ICP. However, no significant differences were observed in the 2-year OS rate (P = 0.267) or the 2-year cumulative incidence of neurological death (P = 0.740).

conclusionsCumulative incidence of ICP was significantly lower with TKI plus RT than with TKI alone; however, there was no significant difference in OS or neurological death. Deferring brain RT may not compromise neurologic and survival outcome in selected patients, but close magnetic resonance imaging follow-up is recommended for patients who defer brain RT.
