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

backgroundIntraoperative hypotension is associated with increased morbidity and mortality after surgery. We hypothesized that intraoperative hypotension might also be associated with worse long-term survival after cancer surgery. Herein, we analyzed the correlation between intraoperative hyper-/hypotension and overall survival after lung cancer surgery.

methodsIn this retrospective cohort study, 676 patients who received lung cancer surgery between January 1, 2006 and December 31, 2009 were reviewed. Intraoperative hyper- and hypotension were defined according to their correlation with long-term survival. The primary endpoint was overall survival. The association between episodes of intraoperative hyper-/hypotension and overall survival was analyzed with multivariable Cox proportional hazard models.

resultsLong-term follow-ups were completed in 515 patients with a median duration of 5.2 years. The estimated 5-year survival rates were 66.5, 61.3, 56.5, and 41.2% in patients with only hypertension (systolic blood pressure > 140 mmHg for ≥5 min), with both hyper- and hypotension (systolic blood pressure < 100 mmHg for ≥5 min), with neither hyper- nor hypotension, and with only hypotension during surgery, respectively. After adjusting confounding factors, intraoperative hypotension was significantly associated with shortened overall survival (compared with patients with only intraoperative hypertension, those with both hyper- and hypotension: hazard ratio [HR]1.033, 95% confidence interval [CI] 0.709 to 1.507, p = 0.864; those with neither hyper- nor hypotension: HR 0.952, 95% CI 0.608 to 1.489, p = 0.829; those with only hypotension: HR 1.736, 95% CI 1.218 to 2.475, p = 0.002).

conclusionsFor patients undergoing lung cancer surgery, intraoperative hypotension, but not hypertension, was associated with shortened overall survival.
