The reporting quality of studies investigating the diagnostic accuracy of anti-CCP antibody in rheumatoid arthritis and its impact on diagnostic estimates.

ABSTRACT:

Background

Recently anti-CCP testing has become popular in the diagnosis of rheumatoid arthritis (RA). However, the inadequate reporting of the relevant diagnostic studies may overestimate and bias the results, directing scientists into making false decisions. The aim of the present study was to evaluate the reporting quality of studies used anti-CCP2 for the diagnosis of RA and to explore the impact of reporting quality on pooled estimates of diagnostic measures.

Methods

PubMed was searched for clinical studies investigated the diagnostic accuracy of anti-CCP. The studies were evaluated for their reporting quality according to STARD statement. The overall reporting quality and the differences between high and low quality studies were explored. The effect of reporting quality on pooled estimates of diagnostic accuracy was also examined.

Results

The overall reporting quality was relatively good but there are some essential methodological aspects of the studies that are seldom reported making the assessment of study validity difficult. Comparing the quality of reporting in high versus low quality articles, significant differences were seen in a relatively large number of methodological items. Overall, the STARD score (high/low) has no effect on the pooled sensitivities and specificities. However, the reporting of specific STARD items (e.g. reporting sufficiently the methods used in calculating the measures of diagnostic accuracy and reporting of demographic and clinical characteristics/features of the study population) has an effect on sensitivity and specificity.

Conclusions

The reporting quality of the diagnostic studies needs further improvement since the study quality may bias the estimates of diagnostic accuracy.

Project description:IntroductionCurrently there is limited data to drive clinical decision making regarding the choice of biologic/targeted synthetic disease-modifying antirheumatic drugs (DMARD); thus, head-to-head comparisons are needed to help guide prescribing. In recent years, significant advancements have helped clarify the mechanistic basis of the clinical associations of autoantibodies in rheumatoid arthritis (RA). This study evaluated the effectiveness of abatacept versus tofacitinib in anti-cyclic citrullinated peptide (CCP+) patients with rheumatoid arthritis (RA).MethodsCorEvitas (formerly known as CORRONA) Registry patients aged ≥ 18 years, who were CCP+ before initiating abatacept or tofacitinib (December 2012 onwards through October 2019), had 6-month follow-up data (baseline and 6-month Clinical Disease Activity Index [CDAI]), and were not in remission at index were included. Patients were frequency matched 1:1 by prior biologic use before propensity score matching (PSM). Primary (mean change [D] in CDAI) and secondary outcomes 6 months after index were compared using mixed-effects models adjusted for variables that remained unbalanced after PSM.ResultsFollowing PSM, most baseline characteristics for 291 patient pairs were well balanced between treatments, although fewer patients initiating abatacept versus tofacitinib received prior non-TNFi biologic DMARDs, and patients initiating abatacept versus tofacitinib had a higher physician global assessment score, patient-reported fatigue, and modified Health Assessment Questionnaire (mHAQ). In adjusted analyses, there were no significant differences in mean [D] from baseline in CDAI at 6 months with abatacept versus tofacitinib (P = 0.936). Patients naïve for b/tsDMARDs initiating abatacept had a numerically greater mean [D] in CDAI at 6 months versus tofacitinib, although this difference was not statistically significant (P = 0.662). There were no significant differences for any secondary outcomes.ConclusionsIn adjusted analyses, CCP+ patients with RA initiating treatment with abatacept versus tofacitinib did not show a statistically significant difference in reducing disease activity or improving patient-reported outcomes.
