Table 2 Comparing the outcomes of interest between the study groups

From: A comparison of nasogastric tube insertion by SORT maneuver (sniffing position, NGT orientation, contralateral rotation, and twisting movement) versus neck flexion lateral pressure in critically ill patients admitted to ICU: a prospective randomized clinical trial

Variables NFLP SORT P
NGT insertion
 Successful 185 (92.5%) 192 (97.0%) 0.046
 Failed 15 (7.5%) 6 (3.0%)  
Complications

 Coiling 23 (11.5%) 23 (11.6%)  
 Multiple 21 (10.5%) 11 (5.6%)  
Ease of insertion
 I 34 (17.0%) 178 (89.9%) < 0.001
 II 130 (65.0%) 14 (7.1%)  
 III 25 (12.5%) 2 (1.0%)  
 IV 11 (5.5%) 4 (2.0%)  
  1. NFLP: neck flexion lateral pressure; SORT: sniffing position, NGT orientation, contralateral rotation, and twisting movement
  2. Ease of insertion:
  3. I: successful insertion in less than 50 s and in first attempt
  4. II: successful insertion in 1st attempt with more than 50 s, or in 2nd attempts with less than 100 s
  5. III: successful insertion in 2nd attempts with more than 100 s, or in 3 attempts
  6. IV: failure
