Methods |
Study design: PCS How were missing data handled? disaggregated attrition analysis was done to identify significant differential attrition and found none. No mention made of ITT analysis, but the footnote to Table A3 indicated the intervention sample as 2098 and control sample as 1940 HHs, which suggests that only HHs that completed the entire follow‐up (2002–2011) were included in analysis as these numbers + total attrition numbers add up to 5626 participants. Randomisation ratio: N/A Recruitment method: NR Sample size justification and outcome used: NR Sampling method: panel data from 4‐round surveys conducted in the Rangpur, Kurigram and Nilphamari districts in Bangladesh used. Participants recruited from extremely poor, with intervention participants recruited through a first‐order community‐based participatory wealth ranking to identify the lowest 10% of the population for income distribution. Authors did not report how recruitment for the panel data survey was done. Study aim or objective: to determine long‐term effects of phase 1 of the CFPR‐TUP programme, predominantly a one‐off transfer of livestock assets, in terms of changes in food expenditure, HH assets, food security and microfinance participation of very poor women in Bangladesh. Study period: panel data obtained at baseline in 2002, interim follow‐up in 2005 and 2008, and final follow‐up in 2011. Unit of allocation or exposure: HHs |

Participants |
Baseline characteristics Intervention or exposure group (n = 2098)
Control group (n = 1940)
Overall group (n = 5626): NR Inclusion criteria: ultra‐poor woman who met ≥ 3 of the following 5 criteria: 1. HH dependent upon female domestic/seasonal work, e.g. begging, maid; 2. own < 10 decimals of land; 3. no active male adult member in HH; 4. no productive assets in HH; and 5. children of school age have to take paid work. Exclusion criteria: no women should have any of the 3 exclusion criteria: 1. no adult woman in the HH who is able to work; 2. participating in microfinance and 3. beneficiary of government/NGO development project. Baseline imbalance: HHs in treatment and control groups differed significantly in many baseline characteristics. Intervention group had fewer cash savings, poorer HH conditions, faced more food deficit, had a smaller number of assets, was more likely to be female headed and had fewer years of education of HH head. Male members from intervention HHs were also less likely be in non‐farm self‐employment, and more likely to be day labourers. Female members of intervention HHs were more likely to be day labourers and servants, and less likely to stay home for HH chores. Attrition per relevant group: 1588 (28.2%) HHs lost to attrition over the total survey period. 895/2993 (20%) were intervention HHs and 693/2633 (26%) were control HHs. Attrition over short‐run (2002–2005) and medium‐run (2002–2008) impact times were NR per group, but total attrition was 398 (7.1%) HHs in 2005 and 1067 (19.0%) HHs in 2008. Description of subgroups measured and reported: none reported Total number completed and analysed per relevant group: footnote to Table A3 indicates the intervention sample as 2098 and control sample as 1940 HHs. This suggests that only HHs that completed the entire follow‐up (2002–2011) were included in analysis. Total number enrolled per relevant group: intervention 2993; control 2633 Total number randomised per relevant group: N/A |

Notes | ||
Risk of bias | ||
Bias | Authors' judgement | Support for judgement |
Random sequence generation (Selection bias) | High risk | CBA, therefore, no randomisation performed. |
Allocation concealment (Selection bias) | High risk | CBA, therefore, no allocation concealment. |
Baseline characteristics similar (Selection bias) | High risk | There were significant differences in characteristics between the groups at baseline. |
Baseline outcome measurements similar (Selection bias) | High risk | Serious baseline imbalance for ownership of natural and physical assets (all P < 0.01 with the exception of number of goat/sheep owned: P < 0.05); food security (all P < 0.01); per capita food expenditure and income (both P < 0.01); and financial market participation (all P < 0.01 with the exception of size of outstanding lending: P < 0.10; NS). |
Blinding of participants and personnel (Performance bias) | Low risk | There was no blinding as this was a CBA but this is unlikely to have influenced the performance of the participants. |
Blinding of outcome assessment (Detection bias) | High risk | There was no blinding. Outcomes were measured with surveys, based on self‐reports from participants. So knowledge of treatment allocation, and perceived benefit or not from this, could have influenced their reporting. |
Protection against contamination (Performance bias) | Unclear risk | Nothing reported regarding how contamination was prevented. It is also unclear who the control groups were so it is difficult to assess potential contamination. |
Incomplete outcome data (Attrition bias) | High risk | Attrition was relatively high for the total follow‐up period; with higher attrition in the intervention compared to the control group (31.4% with intervention vs 25.5% with control). Although reasons for attrition were unrelated to treatment, the characteristics of those who were LTFU and those who remained in the study differed significantly, and the characteristics of people who were LTFU in the intervention and control group were also different. |
Selective outcome reporting (Reporting bias) | Unclear risk | We could access the protocol. In the report of Rabbani et al 2006, some outcomes that are NR in the article were listed such as schooling, purpose of cash borrowing, legal awareness, social inclusion and Eid spending. Note: minor differences in baseline values between Asadullah and Rabbani. |
Other bias | Low risk | None identified. |
