All results are expressed as percentages unless otherwise indicated
Probable depression severity was categorized by PHQ-2 and PHQ-9 screening results. A PHQ-2 score < 2 OR a PHQ-2 score ≥ 3 and a PHQ-9 score < 10 represented a probably non-depressed patient, a PHQ-9 score of 10-14 represented a probably mildly depressed patient, and a PHQ-9 score ≥ 15 represented a probable moderately-to-severely depressed patient
Statistically significant difference between depression screen-negative, screen positive for mild MDD, and screen positive for moderate-to severe MDD groups at p = 0.05 level or below
Sample size too small (n ≤ 5) to report sub-categories
