Mycobacterium W administration for steroid resistant optic neuritis with long-term follow-up.

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
backgroundWe report the long-term safety and outcomes of off-label Mycobacterium W (Mw) administration in steroid resistant optic neuritis.
methodsIn a case series, six patients with documented idiopathic corticosteroid refractory unilateral optic neuritis were treated with immuvac (Mycobacterium W extract). The dose was repeated at three months. Outcomes measures included the best corrected visual acuity (BCVA), pupillary reaction, colour vision, visual field(VF) examination (when possible), fundus examination and photography, and visually evoked potential (VEP) testing. BCVA, pupillary reaction, and color vision were monitored immediately prior to steroid therapy on days 1 and 7 post-steroid therapy, pre-Mw administration (i.e., 30 days after the last dose of steroids had been completed) and post-Mw administration on days 1, 7, 30, 90, 120, and 180. VF, VEP, and fundus photography were performed immediately prior to steroid administration, 30 days after the last dose of steroids (i.e., immediately prior to Mw), and at days 30, 90,120 and, 180. The patients were assessed six-month intervals thereafter for visual acuity, colour vision, and visual fields.
resultsThere were five females and three males in the age range of 30-54 years. Minimum follow-up was five years. All patients showed improvement in visual acuity, colour vision, and pupillary reaction. The patients showed stable improvement. There was no recurrence of the disease and no adverse events till the end of the follow-up period.
conclusionsMw appears to be safe in the long term and to improve steroid resistant optic neuritis; future randomized clinical trials would help affirm this observation.
