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

backgroundEvidence is lacking regarding the potential association between daily variation in individual surgeon's operative time, procedure after procedure, and risk of patient complication. We assumed that surgeon deviation from the expected procedure duration may be harmful for patient.

methodAll patients who underwent a thyroidectomy undertaken in five hospitals during a 1-year period were included prospectively. For each thyroidectomy, we estimated the expected operative time from a multilevel linear regression considering the attending surgeon who performed the operation, the patient preoperative risk, and the procedure complexity. Three groups of thyroidectomies were identified according to whether the observed duration is: slower than expected, as expected, or faster than expected. Rates of permanent recurrent laryngeal nerve palsy and hypoparathyroidism at 6 months were then compared between these groups.

resultsA total of 3102 patients who underwent a thyroidectomy undertaken by 22 surgeons were considered. Risk of laryngeal nerve palsy was higher in the "slow" group than in the "normal" group (OR = 4.63, 95% confidence interval 2.21-9.70), as was that of hypoparathyroidism (OR = 2.43, 95% confidence interval 1.21-4.88). There was no significant difference between "fast" and "normal" groups for either complication. Deviation from expected procedure duration was more frequent at the end than at the beginning of the daily operation schedule (29.4% vs. 18.3%, respectively, P < .001).

conclusionPatients had a greater risk of complication when the surgeon performed thyroidectomy slower than expected. Surgeons avoiding excessive deviations from their expected procedures durations reflect safer practice.
