Role of Vegetarianism, Smoking, and Hydroxocobalamin in Optic Neuritis
Abstract
Only 20 patients with optic neuritis of unknown aetiology could be collected in Bombay over a period of two and a half years. Only six of them were smokers and only three (one a non-smoker) had bilateral centrocaecal scotomata similar to those found in tobacco amblyopia. In 11 untreated patients the serum vitamin B 12 and plasma thiocyanate levels were estimated and found to show no significant differences from those in normal control subjects. Treatment with hydroxocobalamin in the majority of cases and with cyanocobalamin, corticotrophin, or prednisolone in the rest showed equally good results; spontaneous improvement was seen in one case. No significant role could be assigned to smoking (cyanide) or to vegetarianism in the production of optic neuritis in these patients; nor was there any evidence of depletion of total (cyanide-extracted) B 12 or of an increase in the proportion of non-cyanide-extracted B 12 in the serum.

In the citing paper
“Most authors see no significant difference in Vitamin B12 levels in smokers compared with nonsmokers, either in nonpregnant or pregnant individuals (Wadia et al., 1972;Mansoor et al., 1997;Ozerol et al., 2004), although some studies show reduced (Pagan et al., 2001;van Wersch, Janssens & Zandvoort, 2002) or even raised levels of vitamin B 12 in smokers (Tungtrongchitr et al., 2003).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
