Abstract
OBJECTIVE: To determine the effects of various suture patterns on cutaneous blood flow (CBF) at the wound edge as increasing tension is applied through the suture. METHODS: Four different suture patterns commonly used for wound closure (simple, vertical mattress, horizontal mattress, and Allgower-Donati) were placed individually after a full-thickness incision was made in an anesthetized pig. A laser Doppler flowmeter (LDF) was placed on the skin edge after the suture was passed. Baseline CBF was recorded. Increasing tension was applied to the wound edge via the suture through a tensionometer in 0.5-lb (0.23-kg) increments from 0 to 2.5 lb (1.13 kg). CBF was then recorded as a function of tension for each suture pattern. RESULTS: The Allgower-Donati suture pattern affected CBF significantly less than the other three suture patterns did for all tensions from 0.5 to 2.0 lb (0-0.9 kg; P < 0.05). There were no significant differences between vertical mattress, horizontal mattress, and simple suture patterns. CONCLUSIONS: The Allgower-Donati suture pattern had the least effect on CBF with increasing tension in this model. Further study is warranted on the benefits of this suture pattern because it may decrease wound complications in traumatized tissues.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
