1 · What the graph read from 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.

2 · The registry

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

The centromere is the chromosomal site of kinetochore assembly, defined by the histone H3 variant CENP-A. In each cell cycle, the assembly and maintenance of CENP-A is functionally critical for chromosome segregation. In Drosophila male meiosis, CID (fly CENP-A) is assembled in two phases: prophase of meiosis I and postmeiosis II. Here, we investigate the dynamics of the assembly components CAL1 and CENP-C in prophase I and determine the requirements for the second assembly phase. In early prophase I, CENP-C functions with CAL1 to maintain the centromere. In late prophase I, CAL1 is undetectable at centromeres and CENP-C is not critical for centromere maintenance. Instead, CENP-C is crucial for meiotic kinetochore recruitment and function. This CENP-C pool also functions in CID assembly postmeiosis II, which is independent of CAL1. In addition to different functional pools of CENP-C, distinct pools of the CID protein persist in the male germline, and the synthesis of each pool is uncoupled from its cell cycle deposition timing.
