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

purposeThe purpose of this study was to evaluate the impact of tacrolimus drug monitoring parameters on the incidence of acute cellular rejection (ACR) in lung transplant recipients (LTRs).

methodsThis was a retrospective study of patients who underwent lung transplantation at a single center. LTRs who were given tacrolimus during the first 6 months after transplantation and who underwent at least one bronchoscopy with biopsy were included. Tacrolimus time in therapeutic range (TTR) was calculated using Rosendaal's method. Time to therapeutic level, coefficient of variance (CoV), and median trough concentrations were also determined.

resultsThe study included 157 LTRs. ACR ≥ A1 grade was present in 46.5% of patients, and ACR ≥ A2 grade was present in 17.2%. There was no difference between tacrolimus TTR in patients with ACR ≥ A1 compared with those without ACR (47.4 ± 16.1 versus 46.2 ± 18.9%, p = 0.67) or in patients with ACR ≥ A2 grade compared with those with A0 or A1 ACR (46.0 ± 16.3 versus 47.0 ± 17.9%, p = 0.81). When comparing patients with any ACR grade A1 or higher with those without ACR, there was no difference in tacrolimus CoV (42.7 ± 11.0 versus 44.6 ± 12.4, p = 0.30), median tacrolimus trough concentration (9.9 ± 1.3 versus 9.8 ± 1.4 ng/mL, p = 0.66), or days to therapeutic level (9 versus 12 days, p = 0.057).

conclusionsThe results suggest that tacrolimus TTR, time in therapeutic range, and variability are not related to the presence of ACR in LTRs.
