Switching first-line targeted therapy after not reaching low disease activity within 6 months is superior to conservative approach: a propensity score-matched analysis from the ATTRA registry.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTreat-to-target (T2T) is a widely accepted strategy for patients with rheumatoid arthritis (RA). It recommends attaining a goal of at least low disease activity (LDA) within 6 months; otherwise, the current therapy should be modified. We aimed to investigate whether switching a first-line targeted therapy (TT) in patients not reaching LDA within 6 months leads to a higher probability of meeting LDA at the 12-month visit in daily clinical practice using data from Czech registry ATTRA.
methodsWe included patients with RA starting the first-line TT from 1 January 2012 to 31 January 2017 with at least 1-year follow-up. We created four mutually exclusive cohorts based on (1) switching to another TT within the first year and (2) reaching a treatment target (DAS28-ESR ≤ 3.2) at the 6-month visit. The primary outcome was the comparison of odds for reaching remission (REM) or LDA at the 12-month visit between patients switching and not switching TT after not reaching treatment target at 6 months. Before using logistic regression to estimate the odds ratio, we employed the propensity score to match patients at the 6-month visit.
resultsA total of 1275 patients were eligible for the analysis. Sixty-two patients switched within the first 5 months of the treatment before evaluating treatment response at the 6-month visit (C1); 598 patients reached the treatment target within 6 months of therapy (C2); 124 patients did not reach treatment response at 6-month visit and switched to another therapy (C3), and 491 patients continued with the same treatment despite not reaching LDA at the 6-month visit (C4). We matched 75 patients from cohort C3 and 75 patients from C4 using the propensity score. Patients following the T2T principle (C3) showed 2.8 (95% CI 1.4-5.8; p = 0.005) times increased likelihood of achieving REM/LDA at the 12-month visit compared to patients not following the T2T strategy (C4).
conclusionsIn daily clinical practice, the application of the T2T strategy is underused. Switching TT after not reaching REM/LDA within the first 6 months leads to a higher probability of achieving REM/LDA in RA patients at the 12-month visit.
