Historically controlled study |
Non-adherent TB patients |
Yes |
Indirect economic support |
Adherence |
≤32 weeks OR 5.73 [CI 2.25–14.84] ≤52 weeks 7.29 [2.45-22-73] |
Methodological diversity: outcome different than in other studies. |
| Davidson 2000 [56] |
Case-control study |
TB patients |
Yes |
Indirect economic support |
Adherence |
The odds that a patients with 100% adherence under incentives program will adhere 2.7 (1.01100) times as great as person receiving the basic incentive package. |
Methodological diversity: not possible to calculate absolute numbers from the effects. |
| Gelmanova 2011 [66] |
Case series |
TB patients that participated in at least one intervention to improve adherence before referral to the Sputnik program. |
Yes |
Home visits, other psychological and other social support |
Adherence |
Increased from 52.2% [CI 47.5–56.9] to 81.4% [CI 76.8–86.0] |
Methodological and clinical diversity: high risk of bias on the ‘selection’ and ‘outcome’ domain (S2 Table). Study population only includes non-adherent patients, which were their own controls. |

Controlled before–and–after study |
(Poor) Migrant TB patients |
Unclear |
Direct economic support |
Treatment success, loss to follow-up and death. |
Significant reduction of default rates (11% vs 1%, P = 0.03) in intervention district compared to the control district |
This study was part of a bigger study (Zou et al. 2013 [64]), therefore this study was excluded. |
