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

introductionData on prophylactic cranial irradiation (PCI) after complete resection of SCLC are limited. The purpose of this study was to investigate the impact of PCI in this population.

methodsWe retrospectively identified completely resected SCLC at the Shanghai Chest Hospital between January 2006 and January 2014.

resultsA total of 349 patients (115 patients who received PCI [the PCI-treated cohort] and 234 patients who did not [the non-PCI-treated cohort]) were included in the study. The results demonstrated that the PCI-treated cohort had longer overall survival than the non-PCI-treated cohort among patients with pathologic stage (p-stage) II (hazard ratio [HR] = 0.54, 95% confidence interval [CI]: 0.30-0.99, p = 0.047) and p-stage III (HR = 0.54, 95% CI: 0.34-0.86, p = 0.009) disease. Among patients with p-stage III disease, there was a significantly higher risk for cerebral recurrence from the time of diagnosis in the non-PCI-treated cohort (p = 0.018). With regard to patients with p-stage I disease, neither overall survival benefit (HR = 1.61, 95% CI: 0.68-3.83, p = 0.282) nor risk for cerebral recurrence (p = 0.389) was significant between the PCI-treated and non-PCI-treated cohorts.

conclusionsThe data presented in the current study support using PCI in patients with p-stage II/III disease but not in patients with p-stage I disease. A relatively lower risk for brain metastases in p-stage I patients might explain the inferior efficacy of PCI in this population.
