Was the allocation sequence random?
rct_d1_1
|
The document states that patients were 'randomly divided into three groups' and mentions 'block randomization' as the method used. However, there is no explicit description of how the allocation sequence was generated (e.g., computer-generated random numbers, random number tables). The mention of block randomization suggests some level of randomization, but without details on sequence generation, the adequacy of randomization cannot be fully assessed.

some concerns | |
|
Was the allocation sequence concealed until participants were enrolled and assigned to interventions?
rct_d1_2
|
The document mentions randomization but provides insufficient detail about allocation concealment. While the method of randomization is stated as 'block randomization', there is no explicit description of how the allocation sequence was concealed from those recruiting or enrolling participants. This lack of detail raises some concerns about potential bias in the allocation process.
|
some concerns | |
|
Were there baseline imbalances that suggest a problem with randomization?
rct_d1_3
|
The document provides baseline characteristics for the three groups (Table 1) and states that 'No significant differences were noticed among the groups (ANOVA and chi-square test).' However, the document does not explicitly state whether baseline imbalances were assessed for all relevant prognostic factors or whether any adjustments were made for potential imbalances. The reported characteristics include age, sex, skin type, duration of surgery, amount of bleeding, and specifications of operation, but it is unclear if these are the only factors considered or if others were assessed but not reported.

some concerns | |
|
Were participants aware of their assigned intervention during the trial?
rct_d2_1
|
The document does not provide any explicit information about whether participants were aware of their assigned intervention during the trial. There is no mention of participant blinding procedures or any measures taken to prevent participants from knowing which treatment they received. The absence of this critical methodological detail means we cannot assume blinding was implemented.

|
Were carers and people delivering the interventions aware of participants' assigned intervention during the trial?
rct_d2_2
|
The document provides partial information about blinding of care providers but lacks complete methodological details. While it states that 'The surgeons and one of the authors who measured the outcome of the three groups were blinded to the usage of different drug treatments,' it does not explicitly state whether other care providers (e.g., nurses administering medications) were blinded. This creates uncertainty about the full extent of blinding in the trial.

Were there deviations from the intended intervention that arose because of the experimental context?

some concerns | |
|
Was an appropriate analysis used to estimate the effect of assignment to intervention?
rct_d2_4
|
The document does not explicitly state whether an intention-to-treat (ITT) analysis was performed. While it mentions that 'All patients completed the follow-up period and no patient was lost to follow-up in this research,' this does not confirm whether all randomized participants were included in the analysis regardless of protocol deviations or non-compliance. The absence of explicit ITT methodology description creates uncertainty about the analysis approach.
|
some concerns | |
|
Were data for this outcome available for all, or nearly all, participants randomized?
rct_d3_1
|
The document explicitly states that all participants completed the follow-up period with no loss to follow-up, indicating complete outcome data for all randomized participants. This meets the criterion for low risk of bias regarding completeness of outcome data.
|
low risk | |
|
Is there evidence that the result was not biased by missing outcome data?
rct_d3_2
|
The document explicitly states that all patients completed the follow-up period and no patient was lost to follow-up, which directly addresses the potential for bias from missing outcome data. This clear statement provides sufficient evidence that missing data would not impact the observed effect.
|
low risk | |
|
Could missingness in the outcome depend on its true value?
rct_d3_3
|
The document explicitly states that all patients completed the follow-up period and no patient was lost to follow-up, which directly addresses the criterion by indicating there was no missing outcome data that could depend on its true value.

|
Were outcome assessors aware of the intervention received by study participants?
rct_d4_3
|
The document provides partial information about blinding of outcome assessors but lacks complete clarity on whether all assessors were blinded. While it states that 'one of the authors who measured the outcome' was blinded, it does not explicitly confirm whether all outcome assessors were blinded to treatment allocation.
|
some concerns | |
|
Could assessment of the outcome have been influenced by knowledge of intervention received?
rct_d4_4
|
The document provides some information about blinding but lacks sufficient detail about whether outcome assessors were aware of the intervention received. While it states that 'the surgeons and one of the authors who measured the outcome of the three groups were blinded to the usage of different drug treatments,' it does not explicitly confirm whether the photographic assessment was performed by blinded assessors or if the blinding was maintained throughout the outcome assessment process.
|
some concerns | |
|
Were the data that produced this result analyzed in accordance with a pre-specified analysis plan?
rct_d5_1
|
The document does not explicitly mention a pre-specified analysis plan or protocol for data analysis. While the statistical methods are described ('Data were analyzed using SPSS 11.5 for Windows... Chi-square test was used to evaluate preoperative and postoperative ratios in each group and ANOVA was used for comparing average data in the three groups'), there is no explicit statement confirming whether these analyses were pre-specified or if any deviations occurred from a planned analysis.
