Finnerty 1978.
Methods | Double‐blind, randomised study | |
Participants |
Insomnia diagnosis criteria (method of diagnosis): no formal insomnia diagnosis mentioned, instead "Patients with sleep disturbance were considered for treatment." Other diagnoses: neurotic depression and minimum score of 7 on Raskin Scale for Depression Number of participants randomised: n = 139 Doxepin: n = 71 Imipramine: n = 68 Number of participants: n = 97 Doxepin: n = 49 Imipramine: n = 48 Age, mean (range) years: Doxepin: 38.5 (20‐67) Imipramine: 38.6 (19‐65) Gender (M/F): Doxepin: 20/29 Imipramine: 16/32 Race/ethnicity: not reported Country: Boston and Philadelphia, USA Setting: 2 outpatient treatment and research centres Included: people with primary diagnosis of neurotic depression with a minimum score of 7 on the Raskin Scale for depression and with sleep disturbance symptoms. Excluded: people with physical contraindications such as glaucoma, urinary retention, severe organic disease or the potential to become pregnant; history of alcoholism; sensitivity to tricyclic antidepressants; who received MAOIs or any other psychotropic drug in 2 weeks prior to study. Withdrawals: n = 42 Doxepin: n = 22 (failure to keep study visit n = 7: drug toxicity n = 13; intercurrent illness n = 1; violation of protocol n = 1) Imipramine: n = 20 (failure to keep study visit n = 10; drug toxicity n = 10) Baseline imbalances: fewer men than women in the imipramine group and in comparison with the doxepin group |

Notes | ||
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (selection bias) | Low risk | Computer‐generated pattern of randomisation in groups of 4 (Pg 853, second paragraph) |
Allocation concealment (selection bias) | Unclear risk | No details given, but reported double blind |
Blinding of participants and personnel (performance bias) All outcomes | Unclear risk | No details given, but reported double blind |
Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | No details given, but reported double blind |
Incomplete outcome data (attrition bias) All outcomes | High risk | 42/139 participants did not complete the study, i.e. 30% (Pg 853, "Results"); no ITT |
Selective reporting (reporting bias) | High risk | Finnerty‐Goldberg scale used to assess sleep disturbance, but findings not reported in full (Pg 853) |
Other bias | Unclear risk | No disclosure of conflicts of interest |
