[Immunohistochemical determination of cell cycle regulatory proteins. No prognostic significance in advanced squamous epithelial carcinomas of the head-neck area].
Article in HNO, 2003. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundIn recent years, a number of molecular markers have been tested for their potential to predict the outcome after radiotherapy or radiochemotherapy in patients with advanced head and neck squamous cell carcinomas (HNSCC). These studies have produced controversial results. PATIENTS AND
methodsThe expression patterns of the proteins p53, pRb, cyclinD1, cdk4, p21(CIP1/WAF1), p16(INK4a), bcl-2, and mib-1/ki-67 were analyzed in pretreatment tumor biopsies of 53 patients with advanced nonresectable head and neck squamous cell carcinomas (mainly UICC IV). The patterns obtained were compared with clinical outcome after accelerated radiochemotherapy with carboplatin and 5-fluorouracil or accelerated fractionated radiotherapy alone, respectively.
resultsThe expression patterns of the proteins examined did not correlate with response to therapy or with further clinical course.
conclusionIn patients with advanced head and neck squamous cell carcinomas, the prognostic relevance of pretreatment expression patterns of the proteins investigated in this study, particularly p53, cyclinD1, and cdk4, has to be questioned.
