1 · What the graph read from it

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.

2 · The registry

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

backgroundPoor response to anti-tumour necrosis factor biologicals like infliximab (IFX) is observed in patients with ulcerative colitis (UC), which may lead to prolonged morbidity and waste of medical resources. We aimed to look for potential biomarkers of response to IFX in patients with UC who were to undergo IFX induction therapy.

methodsSeventy-two IFX naïve UC patients with partial Mayo (pMayo) score of 4-9 received IFX infusion at weeks 0, 2 and 6 as induction therapy. The pMayo score, trough IFX and C-reactive protein (CRP) concentrations were measured. At week 14, patients who achieved a pMayo score of ≤ 2 with no individual subscore exceeding 1 were judged as responders, while patients who responded, but did not achieve a pMayo score of ≤ 2 were judged as partial responders. Likewise, patients who showed unchanged pMayo score or worsened were judged as non-responders. Patients were followed for up to 3.3 years.

resultsResponse, partial response and no response rates were 40.3, 33.3, and 26.4%, respectively. CRP level at week 2 in responders was significantly lower vs partial-responders (P = 0.0135) or non-responders (P = 0.0084) in spite of similar trough IFX level. Further, the median CRP (week 2/week 0) ratio was significantly lower in patients who responded vs partial-responders or non-responders, 0.06, 0.39 and 1.00, respectively. When the cut-off value was set at 0.19 for the CRP (week 2/week 0) ratio, this ratio could predict partial-responders with 79.1% sensitivity and 75.9% specificity. Patients with the CRP (week 2/week 0) ratio greater than 0.19 were likely to be partial-responder, with odds ratio 10.371 (P < 0.0001; 95% confidence interval 3.596-33.440).

conclusionsIn this study, CRP level at week 2 following initiation of IFX induction therapy appeared to be a clinically relevant biomarker of response to IFX in UC patients.
