Relation between resolution of symptoms (score <2) and eradication of H pylori in the different patient groups
| Subgroup | ||||
|---|---|---|---|---|
| All patients (n=109) | I (n=83) | II (n=95) | III (n=73) | |
| Proportion of patients in whom H pylori was eradicated whose symptoms resolved (sensitivity) | 43/92 (47) | 37/74 (50) | 41/81 (51) | 35/66 (53) |
| Proportion of patients with persisting infection and persisting symptoms (specificity) | 16/17 (94) | 8/9 (89) | 13/14 (93) | 6/7 (86) |
| Predictive value of symptom resolution for eradication of H pylori | 43/44 (98) | 37/38 (97) | 41/42 (98) | 35/36 (97) |
| Predictive value of persistence of symptoms for persisting infection | 16/65 (25) | 8/45 (18) | 13/53 (25) | 6/37 (16) |
Values are expressed as number (%).
Subgroups: I, excluding patients with retrosternal discomfort or reflux as predominant symptoms; II, excluding patients with endoscopic oesophagitis; III, excluding patients with either or both of the above.
