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

backgroundThe purpose of this meta-analysis was to evaluate evidence comparing sleeve lobectomy (SL) and pneumonectomy (PN) in the treatment of non-small cell lung cancer (NSCLC).

methodsThe English literature search was undertaken in January 2018 and included studies dating back to 1996. Comparative studies were identified, evaluating survival, local recurrence, and distant recurrence rates, operative mortality, 30-day mortality, as well as complications. A pooled odds ratio (OR) and 95% confidence intervals (95% CI) were calculated with either the random or fixed-effect model.

resultsA total of 27 studies were identified, with publication dates between 1996 and 2018. These 27 studies included a total of 14,194 patients: 4,145 treated with SL and 10,049 treated with PN. The overall survival was significantly higher in the SL group compared to the PN one at 1, 3, 5 years. In patients with N0 and N1 disease, 5-year survival rates following SL exceeded those following PN. There was no statistically significant difference in the 3-, 5-year overall survival of N2 patients, according to the extent of surgery. The PN group had a higher rate of operative mortality, 30-day mortality and distant recurrence incidence. However, no statistical difference in complications and local recurrence between SL and PN were observed.

conclusionsSL is an effective treatment option for hilar NSCLC with improved long-term survival compared to PN, with no increase of recurrence rate or postoperative complications. Furthermore, N2 disease is an important factor related to survival, and lymph node downstaging is a favorable prognostic factor.
