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

introductionuse of generic drugs is common. However, there is still concern among patients and physicians that brand name drugs are more efficient. The aim of the study was to compare efficacy and tolerance between two forms of cisatracurium: brand name versus generic name.

methodsit´s a crossover, randomized, double-blind physiological trial. Patients admitted for hypoxemic acute respiratory failure with PaO2/FIO2 < 200mmHg despite optimized ventilation and sedation thus requiring non-depolarizing neuromuscular blocking agents (NMBAs), were enrolled. Patients received consecutively, in a random order, cisatracurium brand name (Nimbex®) and generic (Cisatrex®) over two-hour period separated by one-hour washout period. Neuromuscular function was monitored by a calibrated train-of-four (TOF) stimulation device. Paralysis time delay to reach TOF of 2/4, recovery kinetics and tolerance were monitored. The number needed to demonstrate a significant difference in time delays to reach a TOF of 2/4 between the two forms of cisatracurium was estimated at 22 patients.

resultstwenty-two patients were included. Eight (36.4%) had acute respiratory distress syndrome; 8(36.4%), acute exacerbation of chronic obstructive pulmonary disease and 3(13.6%), status asthmaticus. Median [IQR] SAPS II at admission, 28.5 [22, 41]. PaO2/FIO2, 121 [81, 156] mmHg. Paralysis time delays were respectively, 80 [50, 112] vs. 87 [65, 115] minutes, in Nimbex® group and Cisatrex® group; (p=0.579). Within the recovery period, the between two-studied drugs´ difference in TOF was at 0.25±0.96; p=0.64. There were no significant hemodynamic differences.

conclusionthe present study revealed no significant differences in efficacy nor in tolerance between cisatracurium brand name Nimbex® and generic name Cisatrex® in hypoxemic ventilated patients.
