The "Weekday Effect"-Does It Impact Esophageal Cancer Surgery Outcomes?
Article in Journal of gastrointestinal cancer, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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.
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
backgroundIncreased 30-day mortality rates have been reported in patients undergoing elective surgery later compared with earlier in the week. However, these reports have been conflicting for esophageal surgery. We conducted a study to assess the differences in outcomes of patients undergoing surgery for esophageal cancer earlier in the week (Tuesday) versus later (Friday).
methodsThis retrospective analysis of a prospectively maintained database included patients with esophageal cancer who underwent esophageal resection in a tertiary cancer center between 1 January 2005 and 31 December 2017. We compared patients operated on Tuesdays versus Fridays. The primary outcome was a composite of major morbidity (defined as Clavien-Dindo grade 3 or more) and/or mortality. Secondary outcomes included duration of post-operative ventilation, and length of ICU and hospital stay.
resultsAmong 1300 patients included, 733 were operated on a Tuesday and 567 on a Friday. Patient and surgery characteristics were similar in the two groups. The primary outcome (composite of major morbidity and mortality) was 23.6% in the Tuesday group versus 26.3% in the Friday group. Mortality was similar in the two groups (6.0%). Multivariable logistic regression analysis showed that the day of surgery was not a predictor of major morbidity or mortality.
conclusionsIn patients undergoing esophagectomy at tertiary care high volume cancer center, there was no difference in major morbidity and mortality whether the surgery was performed early in the week (Tuesday) or closer to the weekend (Friday).
