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

Sex determination is a critical step in identification. Scarce studies assessed the sexual dimorphism of specific lumbar vertebrae in Egyptians. This prospective study which enrolled 134 Egyptians assessed the sexual dimorphism of lumbar vertebrae using multi-slice computed tomography. At all levels, six vertebral measurements were investigated, including the upper end plate depth (EPDu), the lower end plate depth (EPDl), the upper end plate width (EPWu), the lower end plate width (EPWl), the anterior height of vertebral body (VBHa) and the posterior height of vertebral body (VBHp). The males exhibited significantly greater measurements than females, and EPDu, EPDl, EPWu, and EPWl of L1, EPDl of L2, EPWu of L3, and EPWl of L4 were the best individual sex predictors. We introduced five sex-predicting models showing exceptional area under curves ≥ 0.9. The models incorporating L1 and L2 measurements showed the highest R
