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

Objective: The appearance of our physical features, including our hair, holds great significance in our lives. Shampooing is a widely adopted practice for improving hair condition. However, there is an ongoing debate regarding the impact of shampooing frequency on hair and scalp health. This study aimed to investigate the relationship between the frequency of hair shampooing and the condition of both hair and scalp. Methods: A cross-sectional study design was employed to gather data through online survey questionnaires administered in Arabic and targeted at Saudi Arabian citizens. The study included a sample size of 4796 participants from various clinics across Saudi Arabia. Descriptive statistics were utilized to analyze the data, calculating frequencies and percentages for different groups. Chi-square tests and inferential analysis were conducted to determine the association between variables. Results: The study identified a significant correlation between hair type and hair problems. Long hair and hairstyles with curls were associated with higher rates of hair breakage and daily hair loss. The findings demonstrated that the frequency of hair shampooing directly influenced the condition of both hair and scalp. Increased shampooing frequency was found to improve hair and scalp conditions. Conclusion: In conclusion, this study establishes that a higher frequency of shampooing enhances the condition of both hair and scalp. Therefore, we recommend that individuals aiming to enhance their physical appearance should consider increasing the frequency of shampoo usage.
