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

backgroundPrevious publications revealed more complications in afternoon versus morning surgeries. With much attention given to robotic surgery outcomes, we sought to evaluate whether morning versus afternoon start time matters.

methodsIn a retrospective review of a prospective database, 210 robotic colorectal surgeries were grouped into 97 morning versus 113 afternoon cases. Preoperative risk factors, intraoperative events, and 30-day postoperative outcomes were compared. An independent samples t-test, Fisher's exact test, and linear regression were used for categorical and continuous variables.

resultsMorning patients were significantly younger than afternoon patients (59.5 vs. 65.5, p = 0.004), but there were no significant differences in gender, mean BMI, Charlson Comorbidity Index score, total operative time, console time, estimated blood loss, indications for surgery, and resection type. Morning patients had a significantly shorter mean length of stay (6.0 vs. 8.0 days, p = 0.021), but no significant differences in overall postoperative complications (0.30 vs. 0.30, p = 0.715), wound infection (5.2% vs. 7.1%, p = 0.564), anastomotic leak (0% vs. 2.7%, p = 0.251), ileus/small bowel obstruction (29.9% vs. 22.1%, p = 0.199), and 30-day readmission (8.2% vs. 7.1%, p = 1.000). When analyzing time of day as a continuous variable, we found no significant associations with intra- or postoperative complications.

conclusionWe found no correlation between surgery start time and intra- or postoperative outcomes. This can be partly attributed to these cases being non-emergent and performed primarily by two experienced surgeons with highly trained operating room robotic staff in a large volume tertiary center. This, along with decreased fatigue attributed to superior ergonomics of robotic surgery, may have mitigated previously reported differences between morning and afternoon procedures.
