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

backgroundThis study aimed to assess the surgical difficulty of minimally invasive esophagectomy in the left lateral decubitus position for patients with esophageal cancer from the perspective of short-term outcomes, including operation time, blood loss, and morbidity. MATERIALS AND

methodsThe initial 44 consecutive patients with esophageal cancer who underwent minimally invasive esophagectomy were statistically analyzed retrospectively. Thoracic cage area was measured from preoperative computed tomography as a factor affecting the surgical difficulty of minimally invasive esophagectomy, as well as other patient characteristics. Correlations with short-term outcomes including chest operation time, blood loss, and morbidity rate were then examined.

resultsIn univariate analyses, smaller area of the upper thoracic cage width correlated with prolonged thoracic procedure time (p = 0.0119) and greater blood loss during thoracic procedures (p = 0.0283), but area of the lower thoracic cage showed no correlations. History of respiratory disease was associated with thoracic procedure time (p < 0.0001), but not blood loss. In multivariate analysis, small area of the upper thoracic cage was independently associated with prolonged thoracic procedure time (p = 0.0253). Small upper thoracic cage area was not directly correlated with morbidity rate, but prolonged thoracic procedure time was associated with increased blood loss (p < 0.0001) and morbidity rate (p = 0.0204). Empirical time reduction (p = 0.0065), but not blood loss, was associated with thoracic procedure time. However, area of the upper thoracic cage did not correlate with empirical case number. In multivariate analysis, area of the upper thoracic cage (p = 0.0317) and empirical case number (p = 0.0193) correlated independently with thoracic procedure time.

conclusionA small area of the upper thoracic cage correlated significantly with prolonged thoracic procedure time and increased thoracic blood loss for minimally invasive esophagectomy in the left lateral decubitus position, suggesting the surgical difficulty of minimally invasive esophagectomy in the left lateral decubitus position.
