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

objectiveNeoadjuvant chemotherapy improves resectability rates of oesophageal cancer, but the process may also take a toll on the patients' exercise capacity and may adversely affect the postoperative outcomes. It can be assessed objectively using cardiopulmonary exercise testing.

methodsPatients with oesophagus cancer performed a baseline test and a second test after neoadjuvant chemotherapy during the week preceding oesophagectomy. They were followed up for postoperative complications, length of hospital stay, and 30-day mortality.

resultsThirty-three patients completed the study. The mean pre-chemotherapy peak oxygen uptake (VO2 peak) was 1128.39 ± 202.79 mL min-1 (19.46 ± 3.06 mL kg-1 min-1 ) which declined to 1010.33 ± 195.56 mL min-1 (17.24 ± 2.55 mL kg-1 min-1 ) in the postchemotherapy period (P < .001). Pre-chemotherapy anaerobic threshold was 906.85 ± 176.81 mL min-1 (15.54 ± 2.24 mL kg-1 min-1 ) which declined to 764.76 ± 158.79 mL min-1 (13.01 ± 2.22 mL kg-1 min-1 ) (P < .001) in the post-chemotherapy period. Six patients developed complications of modified Clavien-Dindo grade 3 and above. Two (6.1%) patients succumbed to complications within 30 days. The mean anaerobic threshold in patients who suffered complications modified Clavien-Dindo grade ≥3 was 693.33 ± 140.99 mL min-1 (11.2 ± 1.17 mL kg-1 min-1 ) while patients with mild to moderate complications had a mean anaerobic threshold 13.41 ± 2.21 mL kg-1 min-1 (P < .006). An optimal cut off value for anaerobic threshold was 12.5 mL kg-1 min-1 Conclusion: Cardiopulmonary exercise testing accurately predicts outcomes in cancer oesophagus patients who undergo neoadjuvant chemotherapy followed by surgery.
