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

backgroundIn patients with clinical N1 disease, minimally invasive surgery (MIS) has potentially better perioperative outcome compared to open thoracotomy. Additionally, whether adjuvant or neoadjuvant chemotherapy produces the best long-term survival is still debatable.

methodsWe queried The National Cancer Database for patients with clinical N1 NSCLC who underwent surgical resection between 2010 and 2014. Comparison between patients receiving MIS and patients who underwent open thoracotomy was done using an intention-to-treat analysis. Comparison was also done among neoadjuvant, adjuvant chemotherapy, and only surgery. Proportional hazard models were used to evaluate the effects of surgical approach and timing of chemotherapy on overall survival.

resultsA total of 1440 and 3942 patients underwent MIS and open thoracotomy respectively. MIS achieved better surgical margins (90.0% versus 88.6%) and shorter length of stay (6.5 ± 6.5 versus 7.3 ± 6.4 d, P ≤ 0.01) compared to open thoracotomy. There were no differences in 30-day and 90-day mortality, nor readmission rates. Neoadjuvant and adjuvant chemotherapy were administered to 13.5% and 57.2% of patients respectively. There was no significant difference in the 5-year overall survival between MIS and open thoracotomy (46% versus 46% P = 0.08). There was significantly better 5-year overall survival in neoadjuvant and adjuvant chemotherapy versus only surgery, but no difference between neoadjuvant and adjuvant chemotherapy (48% versus 47% versus 44%, P < 0.01).

conclusionsIn clinical N1 NSCLC, MIS does not compromise oncological quality or overall survival when compared to open thoracotomy. Overall survival improved in patients treated with chemotherapy but there is no difference when given as neoadjuvant versus adjuvant chemotherapy.
