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

purposeTransdermal buprenorphine patches provide comparable pain relief to that of low-potency opioids in elderly individuals. However, specific data on their use in elderly individuals is limited. This study investigated and compared the PK of buprenorphine transdermal patches in elderly (≥ 75 years) versus younger (50-60 years) individuals.

methodsThis was a multiple-dose, open-label, parallel-group study in healthy volunteers split into two age groups (younger, 50-60 years; elderly, ≥ 75 years) with 37 individuals in each. Study participants received two consecutive 7-day buprenorphine 5 μg/h transdermal patch applications, and blood samples were collected on the week of the second patch application [day 7 (predose), days 8, 9, 10, 12, and 14] to determine PK at steady state. Pharmacokinetic parameters were determined for buprenorphine and norbuprenorphine. Safety was assessed by analyzing adverse events, hematology, clinical chemistry, urine analysis, vital signs, electrocardiogram (ECG), and physical examinations.

resultsThe area under the plasma concentration-time curve at steady state (AUC(tau)), measured over one dosing interval, was similar for elderly [mean ± standard deviation (SD) 9,940 pg/h/ml (4,827 pg/h/ml] and younger [mean ± SD 11,309 (3,670 pg/h/ml] individuals. Bioequivalence was not demonstrated between groups, which may be attributable to the relatively high level of variability in individual plasma profiles. More adverse events were reported by younger (216) than elderly (164) study participants.

conclusionsNo dosage alterations are necessary for PK reasons when treating elderly people with buprenorphine transdermal patches.
