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
backgroundInduction of septic shock by lipopolysaccharide (LPS) may lead to acute renal failure. The present study aimed to investigate the impact of sex differences on the effectiveness of low-dose LPS preconditioning (LPS-PC) on LPS-induced acute renal failure in rats.
methodsThis study was conducted at Tehran University of Medical Sciences, in 2017. A total of 48 Wistar rats were equally divided into two groups of male and female rats. The rats in each group were then allocated to three groups (n=8 per group), namely control, septic shock, and LPS-PC group. A high dose of LPS was administered for septic shock induction. LPS-PC was induced by injecting LPS before sepsis induction. The effect of sex differences on renal functional indices, renal oxidative stress markers, plasma tumor necrosis factor-α level, and renal histological changes was evaluated. Data were analyzed using two-way ANOVA followed by Tukey's
resultsIn the septic shock groups, renal functional parameters (creatinine [Cr] and blood urea nitrogen [BUN]) were increased in both sexes. However, the increase was more significant in male rats (male rats: Cr=2.14±0.13, BUN=81±4.15; female rats: Cr=1.64±0.12, BUN=50±2.7). LPS-PC reduced these indices in both sexes (male rats: Cr=1.24±0.03, BUN=57±4.1; female rats: Cr=0.86±0.02, BUN=30.31±2.25). Renal superoxide dismutase (SOD) activity (male rats: 11.54±1.34, female rats: 24.4±2.04) and catalase (CAT) activity (male rats: 15±1.74, female rats: 25.75±1.97) were significantly higher in the female septic group. LPS-PC significantly increased SOD (male rats: 25.7±2.45, female rats: 42.6±3.31) and CAT (male rats: 37.25±2.34, female rats: 59.21±3.29) activities in renal tissue samples in the LPS-PC group in both sexes compared to the septic groups. In the LPS groups, plasma tumor necrosis factor-α (male rats: 375±25.65, female rats: 285.45±25.94) were significantly higher than in the LPS-PC groups (male rats: 250±21.35, female rats: 121±24.14).
conclusionMale rats were more susceptible to sepsis-induced renal damage. LPS-PC had protective effects on the LPS-induced renal injury, and these effects were most prominent in female rats.
