WITHDRAWN: Medicinal herbs for esophageal cancer.
Synthesis in The Cochrane database of systematic reviews, 2007. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEsophageal cancer is the seventh leading cause of cancer death worldwide. Traditional Chinese medicinal herbs are sometimes used as an adjunct to radiotherapy or chemotherapy for this type of cancer.
objectivesTo assess the efficacy and possible adverse effects of the addition of Chinese medicinal herbs to treatment with radiotherapy or chemotherapy for esophageal cancer. SEARCH STRATEGY: We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group Trials Register, The Cochrane Library, MEDLINE, EMBASE, AMED (Allied and Complementary Medicine Database), CBM (Chinese Biomedical Database), China National Knowledge Infrastructure, the Chinese Cochrane Centre Controlled Trials Register and CISCOM (The Research Council for Complementary Medicine) (up to June 2004). Databases of ongoing trials, the internet and reference lists were also searched. SELECTION CRITERIA: Randomised controlled trials comparing the use of radiotherapy or chemotherapy with and without the addition of Chinese medicinal herbs. DATA COLLECTION AND ANALYSIS: At least two review authors extracted data and assessed trial quality. MAIN
resultsWe identified 43 trials which claimed to use random allocation. Sixteen study authors were contacted by telephone and we discovered that they misunderstood the randomisation procedure and the trials were identified as non-RCTs. The situation of lack of authentic randomised controlled trial leads us cannot draw a conclusion to recommend or against the use of TCM as a treatment for esophageal cancer. AUTHORS'
conclusionsThere was no evidence of effect of TCM in the treatment of esophageal cancer due to no any authentic RCT in this field yet. New trials should be large scaled, correctly randomised and results assessor blinded in the future.
