Yoga for epilepsy.
Synthesis in The Cochrane database of systematic reviews, 2000. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 2 of them syntheses that pooled 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.
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
backgroundStress is considered an important precipitating factor for seizures. Yoga is believed to induce relaxation and stress reduction. The effect of yoga on the EEG and the autonomic nervous system have been reported. Yoga would be an attractive therapeutic option for epilepsy (if proved effective), in view of its nonpharmacological nature, minimal side effects and international acceptance.
objectivesTo assess the efficacy of yoga in the treatment of patients with epilepsy. SEARCH STRATEGY: We searched the Cochrane Epilepsy Group trial register, the Cochrane Controlled Trials Register (The Cochrane Library Issue 4, 1998), MEDLINE for articles published up to the middle of 1998, and also registries of the research council for complimentary medicine were searched. In addition, we searched the references of all the identified studies. Finally, we contacted the members of the Neurological Society of India, several neurophysiology institutions and yoga institutes to seek any ongoing studies or studies published in nonindexed journals or unpublished studies. SELECTION CRITERIA: Randomized control trials and controlled clinical trials of treatment of epilepsy with yoga. DATA COLLECTION AND ANALYSIS: The data were extracted independently by both reviewers and any discrepancies were resolved by discussion. The main outcomes assessed were percentage of patients rendered seizure free, number of patients with more than 50% reduction in seizure frequency or seizure duration and the overall reduction in seizure frequency. Analyses were on an intention to treat basis. MAIN
resultsOnly one study met the selection criteria, and recruited a total of 32 patients, 10 to sahaja yoga and 22 to control treatments. Antiepileptic drugs were continued in all. Randomization was by roll of a dice. The results of this study are as follows: (i) Four patients treated with yoga were seizure free for six months compared to none in the control groups. The Odds Ratio (OR) (95% Confidence Interval (CI)) for yoga versus sham yoga group was 14.5 (0.7, 316.7) and for yoga versus no treatment group 17.3 (0.8, 373.5). (ii) Nine patients in the yoga group had more than 50% reduction in seizure frequency compared to only one among the controls. The OR (95% CI) for yoga versus sham yoga group was 81 (4.4, 1504.5) and for the yoga versus no treatment group was 158.3 (5.8, 4335.9). (iii) There was a decline in the average number of attacks per month compared to the baseline frequency among the patients treated with yoga. The weighted mean difference ( 95% CI) between yoga versus sham yoga group was -2.1 (-3.1, -1.0) and for the yoga versus no treatment group -1.1 (-1.8, -0.4). (iv) More than 50% reduction in seizure duration was found in seven of the 10 patients treated with yoga, compared to none among the 22 controls. The OR (95%CI) for yoga versus sham yoga group was 45 (2.0, 1006.8) and for yoga versus no treatment group 53.57 (2.4, 1187.3). REVIEWER'S
conclusionsNo reliable conclusions can be drawn regarding the efficacy of yoga as a treatment for epilepsy. Further studies are necessary to evaluate the efficacy of yoga in the treatment of epilepsy.
