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
Single nucleotide polymorphism (SNP) rs17849071 was recently reported to be inversely associated with PIK3CA amplification in follicular thyroid cancer, but the main function of this SNP remains unclear. In this study, by using PCR and sequencing method, we explored whether this SNP was associated with P53 expression status and other clinicopathological characteristics in 62 Chinese breast cancer (BCa) patients. In our results, P53 protein accumulation was significantly associated with HER2 overexpression (P = 0.013) and Ki-67 expression (P = 0.007), which were in accord with previous studies. Besides, there was a significantly inverse relationship between P53 protein expression and rs17849071 GT+GG genotype in Chinese BCa patients (P = 0.044). The SNP was not related to other important BCa markers such as estrogen receptor, progestin receptor, and HER2. Among different BCa intrinsic subtypes, no significant differences were found on P53 expression status (P = 0.356) or rs17849071 polymorphism (T>G) (P = 0.813). In conclusion, SNP rs17849071 GT+GG genotype was inversely associated with P53 protein accumulation in BCa samples. Studies with larger sample size focusing on exploring the relationship of rs17849071 polymorphisms, P53 accumulation, P53 mutations, and PIK3CA amplification might be needed.
